Question

sovle the equation (x+7)(x+3)=0

Answer 1

x = -7

x = -3

Answer 2

cuz
(-7+7)(x+3) = 0
and
(x+7)(-3+3)=0

Answer 3

To solve it you would set each part equal to 0 and solve. So you'd do
x+7=0
and
x+3=0
And then solve for x for each.

That's how you do it for when you have another instance of that question.
