First you need to foil these terms
(x+10)(x-3)
 X^2+7x-30=0
transpose zero to the other side
X^2+7x-30-0
so.. the answer is
X^2+7x-30
hope it helps...

Solve for the roots (x):

(x + 10) (x - 3) = 0

x + 10 = 0                x - 3 = 0
x₁ = -10                   x₂ = 3

Transform the equation to standard form:
(x + 10) (x -3) = 0
x² + 7x - 30 = 0    ⇒   Standard form
