Question:
What is a polynomial?

Answer:
A polynomial is an algebraic expression consisting of variables, coefficients, and exponents, combined using addition, subtraction, and multiplication. For example, 3x² + 2x - 5 is a polynomial.

Question:
What is the degree of the polynomial 4x³ + 3x² - 2x + 7?

Answer:
The degree of the polynomial 4x³ + 3x² - 2x + 7 is 3 because the highest power of the variable x is 3.

Question:
What is the factorization of x² - 5x + 6?

Answer:
The factorization of x² - 5x + 6 is (x - 2)(x - 3).

Question:
How do you solve the equation 2x - 3 = 5?

Answer:
To solve the equation 2x - 3 = 5, first add 3 to both sides to get 2x = 8, and then divide by 2 to get x = 4.

Question:
What is the quadratic formula?

Answer:
The quadratic formula is used to solve quadratic equations and is given by x = [-b ± √(b² - 4ac)] / 2a, where a, b, and c are coefficients in the equation ax² + bx + c = 0.

Question:
What are like terms in an expression?

Answer:
Like terms in an expression are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.

Question:
What is the difference between a monomial and a binomial?

Answer:
A monomial is an algebraic expression with only one term, like 3x, while a binomial has two terms, like 2x + 5.

Question:
What is the formula for the area of a circle?

Answer:
The formula for the area of a circle is A = πr², where r is the radius of the circle.

Question:
What is the Pythagorean theorem?

Answer:
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. It is written as a² + b² = c².

Question:
What is the perimeter of a rectangle?

Answer:
The perimeter of a rectangle is given by the formula P = 2(l + b), where l is the length and b is the breadth of the rectangle.

Question:
How do you find the volume of a cube?

Answer:
The volume of a cube is calculated using the formula V = a³, where a is the length of the edge of the cube.

Question:
What is the formula for the surface area of a sphere?

Answer:
The surface area of a sphere is given by the formula A = 4πr², where r is the radius of the sphere.

Question:
What is the distance formula in coordinate geometry?

Answer:
The distance formula is used to calculate the distance between two points (x₁, y₁) and (x₂, y₂) in a coordinate plane, and is given by √[(x₂ - x₁)² + (y₂ - y₁)²].

Question:
What is the midpoint formula in coordinate geometry?

Answer:
The midpoint formula is used to find the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂), and is given by [(x₁ + x₂)/2, (y₁ + y₂)/2].

Question:
What are the properties of parallel lines?

Answer:
Parallel lines are lines that never intersect and are always the same distance apart. They have the same slope in a coordinate plane.

Question:
What is an arithmetic progression (AP)?

Answer:
An arithmetic progression is a sequence of numbers in which the difference between consecutive terms is constant. For example, 3, 6, 9, 12 is an AP with a common difference of 3.

Question:
What is the sum of the first n terms of an arithmetic progression?

Answer:
The sum of the first n terms of an arithmetic progression is given by the formula Sₙ = n/2 [2a + (n - 1)d], where a is the first term and d is the common difference.

Question:
What is a geometric progression (GP)?

Answer:
A geometric progression is a sequence of numbers in which each term after the first is found by multiplying the previous term by a constant called the common ratio. For example, 2, 4, 8, 16 is a GP with a common ratio of 2.

Question:
What is the sum of the first n terms of a geometric progression?

Answer:
The sum of the first n terms of a geometric progression is given by the formula Sₙ = a(1 - rⁿ) / (1 - r), where a is the first term and r is the common ratio.

Question:
What is the probability of an event?

Answer:
The probability of an event is the measure of the likelihood of the event happening, and is calculated as the ratio of the favorable outcomes to the total number of possible outcomes.

Question:
What is the formula for the combination of n items taken r at a time?

Answer:
The formula for the combination of n items taken r at a time is C(n, r) = n! / [r!(n - r)!], where n! represents the factorial of n.

Question:
What is the difference between permutation and combination?

Answer:
A permutation is an arrangement of items in a specific order, while a combination is a selection of items without regard to the order.
