Simplifying
135 = (2x + 3)(2x + -3)
Reorder the terms:
135 = (3 + 2x)(2x + -3)
Reorder the terms:
135 = (3 + 2x)(-3 + 2x)
Multiply (3 + 2x) * (-3 + 2x)
135 = (3(-3 + 2x) + 2x * (-3 + 2x))
135 = ((-3 * 3 + 2x * 3) + 2x * (-3 + 2x))
135 = ((-9 + 6x) + 2x * (-3 + 2x))
135 = (-9 + 6x + (-3 * 2x + 2x * 2x))
135 = (-9 + 6x + (-6x + 4x2))
Combine like terms: 6x + -6x = 0
135 = (-9 + 0 + 4x2)
135 = (-9 + 4x2)
Solving
135 = -9 + 4x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x2' to each side of the equation.
135 + -4x2 = -9 + 4x2 + -4x2
Combine like terms: 4x2 + -4x2 = 0
135 + -4x2 = -9 + 0
135 + -4x2 = -9
Add '-135' to each side of the equation.
135 + -135 + -4x2 = -9 + -135
Combine like terms: 135 + -135 = 0
0 + -4x2 = -9 + -135
-4x2 = -9 + -135
Combine like terms: -9 + -135 = -144
-4x2 = -144
Divide each side by '-4'.
x2 = 36
Simplifying
x2 = 36
Take the square root of each side:
x = {-6, 6}
