WebIf we use the quadratic formula, x = − b ± b 2 − 4 a c 2 a, x = − b ± b 2 − 4 a c 2 a, to solve a x 2 + b x + c = 0 a x 2 + b x + c = 0 for the x-x-intercepts, or zeros, we find the value of x …

Intercept form Quadratic — Explanation and Examples

WebTo find an x -intercept, we substitute y = 0 y = 0 into the equation. In other words, we will need to solve the equation 0 = ax2 + bx + c 0 = a x 2 + b x + c for x x. y = ax2 + bx + c 0 = ax2 +bx + c y = a x 2 + b x + c 0 = a x 2 + b x + c But solving quadratic equations like this is exactly what we have done earlier in this tutorial.
