Answer:

(-2,0)

Set up quadratic

[tex]y = 5 {x}^{2} + 5x - 10[/tex]

Divide each coefficient by 5

[tex]y = {x}^{2} + x - 2[/tex]

Factor using AC method.

Think of a number that multiply -2 and add to 1. The answer is -1 and 2.

So we write the equation as

[tex](x - 1)(x +2 )[/tex]

Set each parenthesis to zero.

[tex]x = 1[/tex]

[tex]x = - 2[/tex]

The other zero is -2
