Webb6 okt. 2024 · Use the coefficients of a quadratic equation to help decide which method is most appropriate for solving it. While the quadratic formula always works, it is sometimes not the most efficient method. If given any quadratic equation in standard form, \(a x^{2}+b x+c=0\) where \(c=0\), then it is best to factor out the GCF and solve by factoring. WebbQuadratic Formula. The solutions to a quadratic equation of the form ax2 + bx + c = 0, a ≠ 0 are given by the formula: x = −b ± √b2 − 4ac 2a. To use the Quadratic Formula, we substitute the values of a, b, andc into the expression on the right side of the formula. Then, we do all the math to simplify the expression.
