Target SQE A: Solve a quadratic equation. (Factoring, Completing the Square, Using Square roots, Quadratic Formula)
Slide & Coincide Move the slider for //a// & //b// values which correspond to the red quadratic function which is in intercept form //f//(//x//) = (//x// − //a//)( //x// − //b//) and match it to the blue quadratic function which is in standard form //f//(//x//) = //ax// 2 + //bx// + //c//. media type="custom" key="27718317"

1. What do the values of //a// and //b// represent on the graph?

2. What do the values of //a// and //b// represent for the function?

3. What are the solution(s) to the equation 0 = //x// 2 + 7//x// + 12?

4. What are the solution(s) to the equation //x// 2 + 11//x// = 0

5. What are the solution(s) to the equation 0 = //x// 2 - 81?

6. What are the solution(s) to the equation // x // 2 + 3 // x // + 5 = 0?
