(-3-x)(-x+3)=

Solution for (-3-x)(-x+3)= equation:

Simplifying
(-3 + -1x)(-1x + 3) = 0

Reorder the terms:
(-3 + -1x)(3 + -1x) = 0

Multiply (-3 + -1x) * (3 + -1x)
(-3(3 + -1x) + -1x * (3 + -1x)) = 0
((3 * -3 + -1x * -3) + -1x * (3 + -1x)) = 0
((-9 + 3x) + -1x * (3 + -1x)) = 0
(-9 + 3x + (3 * -1x + -1x * -1x)) = 0
(-9 + 3x + (-3x + 1x2)) = 0

Combine like terms: 3x + -3x = 0
(-9 + 0 + 1x2) = 0
(-9 + 1x2) = 0

Solving
-9 + 1x2 = 0
