Question

Write a quadratic equation in standard form that has two solutions, -5 and 7

Answer 1

`{b}^(2) - {2b} - 35`

Explanation:

1) find two factors of c that sum up to -2.

2) 5 and -7 are factors of -35 that sum up to -2.

3) (x+5)(x-7)

4) x+5= 0, x= -5

5) x-7= 0, x= 7

4) the two solutions are -5 and 7.
