Solution for (x+4)(x-6)=(2x+1)(x-6) equation:


Simplifying
(x + 4)(x + -6) = (2x + 1)(x + -6)

Reorder the terms:
(4 + x)(x + -6) = (2x + 1)(x + -6)

Reorder the terms:
(4 + x)(-6 + x) = (2x + 1)(x + -6)

Multiply (4 + x) * (-6 + x)
(4(-6 + x) + x(-6 + x)) = (2x + 1)(x + -6)
((-6 * 4 + x * 4) + x(-6 + x)) = (2x + 1)(x + -6)
((-24 + 4x) + x(-6 + x)) = (2x + 1)(x + -6)
(-24 + 4x + (-6 * x + x * x)) = (2x + 1)(x + -6)
(-24 + 4x + (-6x + x2)) = (2x + 1)(x + -6)

Combine like terms: 4x + -6x = -2x
(-24 + -2x + x2) = (2x + 1)(x + -6)

Reorder the terms:
-24 + -2x + x2 = (1 + 2x)(x + -6)

-24 + -2x + x2 = (1 + 2x)(-6 + x)

Multiply (1 + 2x) * (-6 + x)
-24 + -2x + x2 = (1(-6 + x) + 2x * (-6 + x))
-24 + -2x + x2 = ((-6 * 1 + x * 1) + 2x * (-6 + x))
-24 + -2x + x2 = ((-6 + 1x) + 2x * (-6 + x))
-24 + -2x + x2 = (-6 + 1x + (-6 * 2x + x * 2x))
-24 + -2x + x2 = (-6 + 1x + (-12x + 2x2))
