(4x-3)(x+3)=

Solution for (4x-3)(x+3)= equation:

Simplifying
(4x + -3)(x + 3) = 0

Reorder the terms:
(-3 + 4x)(x + 3) = 0

Reorder the terms:
(-3 + 4x)(3 + x) = 0

Multiply (-3 + 4x) * (3 + x)
(-3(3 + x) + 4x * (3 + x)) = 0
((3 * -3 + x * -3) + 4x * (3 + x)) = 0
((-9 + -3x) + 4x * (3 + x)) = 0
(-9 + -3x + (3 * 4x + x * 4x)) = 0
(-9 + -3x + (12x + 4x2)) = 0

Combine like terms: -3x + 12x = 9x
(-9 + 9x + 4x2) = 0

Solving
-9 + 9x + 4x2 = 0
