(4x+3)(x-5)=

Solution for (4x+3)(x-5)= equation:

Simplifying
(4x + 3)(x + -5) = 0

Reorder the terms:
(3 + 4x)(x + -5) = 0

Reorder the terms:
(3 + 4x)(-5 + x) = 0

Multiply (3 + 4x) * (-5 + x)
(3(-5 + x) + 4x * (-5 + x)) = 0
((-5 * 3 + x * 3) + 4x * (-5 + x)) = 0
((-15 + 3x) + 4x * (-5 + x)) = 0
(-15 + 3x + (-5 * 4x + x * 4x)) = 0
(-15 + 3x + (-20x + 4x2)) = 0

Combine like terms: 3x + -20x = -17x
(-15 + -17x + 4x2) = 0

Solving
-15 + -17x + 4x2 = 0

Solving for variable 'x'.
