Answer this question (x - 2) (x + 5) = 18

x=-7 x=4

Step-by-step explanation:

(x - 2) (x + 5) = 18

Foil

x^2 + 5x-2x-10 = 18

Combine like terms

x^2 + 3x - 10 = 18

Subtract 18 from each side

x^2 + 3x - 28 = 0

Factor

What two numbers multiply to - 28 and add to 3: 7 and - 4

(x+7) (x-4) = 0

Using the zero product property

x+7=0 x-4 = 0

x=-7 x=4
