Solution for (x-4)(x-10)=24x equation:


Simplifying
(x + -4)(x + -10) = 24x

Reorder the terms:
(-4 + x)(x + -10) = 24x

Reorder the terms:
(-4 + x)(-10 + x) = 24x

Multiply (-4 + x) * (-10 + x)
(-4(-10 + x) + x(-10 + x)) = 24x
((-10 * -4 + x * -4) + x(-10 + x)) = 24x
((40 + -4x) + x(-10 + x)) = 24x
(40 + -4x + (-10 * x + x * x)) = 24x
(40 + -4x + (-10x + x2)) = 24x

Combine like terms: -4x + -10x = -14x
(40 + -14x + x2) = 24x

Solving
40 + -14x + x2 = 24x

Solving for variable 'x'.

Reorder the terms:
40 + -14x + -24x + x2 = 24x + -24x

Combine like terms: -14x + -24x = -38x
40 + -38x + x2 = 24x + -24x

Combine like terms: 24x + -24x = 0
40 + -38x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-40' to each side of the equation.
40 + -38x + -40 + x2 = 0 + -40

Reorder the terms:
40 + -40 + -38x + x2 = 0 + -40

Combine like terms: 40 + -40 = 0
0 + -38x + x2 = 0 + -40
-38x + x2 = 0 + -40
