Solution for (x+3)(x-2)=36 equation:

Simplifying
(x + 3)(x + -2) = 36

Reorder the terms:
(3 + x)(x + -2) = 36

Reorder the terms:
(3 + x)(-2 + x) = 36

Multiply (3 + x) * (-2 + x)
(3(-2 + x) + x(-2 + x)) = 36
((-2 * 3 + x * 3) + x(-2 + x)) = 36
((-6 + 3x) + x(-2 + x)) = 36
(-6 + 3x + (-2 * x + x * x)) = 36
(-6 + 3x + (-2x + x2)) = 36

Combine like terms: 3x + -2x = 1x
(-6 + 1x + x2) = 36

Solving
-6 + 1x + x2 = 36

Solving for variable 'x'.
