Solution for (4x+5)(x-2)=4x(x-2) equation:


Simplifying
(4x + 5)(x + -2) = 4x(x + -2)

Reorder the terms:
(5 + 4x)(x + -2) = 4x(x + -2)

Reorder the terms:
(5 + 4x)(-2 + x) = 4x(x + -2)

Multiply (5 + 4x) * (-2 + x)
(5(-2 + x) + 4x * (-2 + x)) = 4x(x + -2)
((-2 * 5 + x * 5) + 4x * (-2 + x)) = 4x(x + -2)
((-10 + 5x) + 4x * (-2 + x)) = 4x(x + -2)
(-10 + 5x + (-2 * 4x + x * 4x)) = 4x(x + -2)
(-10 + 5x + (-8x + 4x2)) = 4x(x + -2)

Combine like terms: 5x + -8x = -3x
(-10 + -3x + 4x2) = 4x(x + -2)

Reorder the terms:
-10 + -3x + 4x2 = 4x(-2 + x)
-10 + -3x + 4x2 = (-2 * 4x + x * 4x)
-10 + -3x + 4x2 = (-8x + 4x2)

Add '-4x2' to each side of the equation.
-10 + -3x + 4x2 + -4x2 = -8x + 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-10 + -3x + 0 = -8x + 4x2 + -4x2
-10 + -3x = -8x + 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-10 + -3x = -8x + 0
-10 + -3x = -8x
