Understanding Quadratic Equations
A quadratic equation is a second-degree polynomial equation of the form:
ax2+bx+c=0ax^2 + bx + c = 0
where a,b,ca, b, c are real numbers and a≠0a \neq 0. The solutions, known as roots, can be found using factorization, completing the square, or the quadratic formula:
x=−b±b2−4ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
