Quadratic Equations: - video-tutor. net This chapter provides video lessons on quadratic equations It covers topics on solving quadratic equations by factoring and by using the quadratic formula It also explains how to solve quadratic equations by completing the square and by using the zero
The quadratic formula | Algebra (video) | Khan Academy The quadratic formula helps us solve any quadratic equation First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients Then, we plug these coefficients in the formula: (-b±√(b²-4ac)) (2a) See examples of using the formula to solve a variety of equations
