Solution for (x-4)*(2x-3)=2x*2x equation:


Simplifying
(x + -4)(2x + -3) = 2x * 2x

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

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

Multiply (-4 + x) * (-3 + 2x)
(-4(-3 + 2x) + x(-3 + 2x)) = 2x * 2x
((-3 * -4 + 2x * -4) + x(-3 + 2x)) = 2x * 2x
((12 + -8x) + x(-3 + 2x)) = 2x * 2x
(12 + -8x + (-3 * x + 2x * x)) = 2x * 2x
(12 + -8x + (-3x + 2x2)) = 2x * 2x

Combine like terms: -8x + -3x = -11x
(12 + -11x + 2x2) = 2x * 2x

Reorder the terms for easier multiplication:
12 + -11x + 2x2 = 2 * 2x * x

Multiply 2 * 2
12 + -11x + 2x2 = 4x * x

Multiply x * x
12 + -11x + 2x2 = 4x2

Solving
12 + -11x + 2x2 = 4x2

Solving for variable 'x'.

Combine like terms: 2x2 + -4x2 = -2x2
12 + -11x + -2x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
12 + -11x + -2x2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-6 + 5.5x + x2 = 0

Move the constant term to the right:

Add '6' to each side of the equation.
-6 + 5.5x + 6 + x2 = 0 + 6

Reorder the terms:
-6 + 6 + 5.5x + x2 = 0 + 6

Combine like terms: -6 + 6 = 0
0 + 5.5x + x2 = 0 + 6
5.5x + x2 = 0 + 6

Combine like terms: 0 + 6 = 6
5.5x + x2 = 6

The x term is 5.5x.  Take half its coefficient (2.75).
Square it (7.5625) and add it to both sides.

Add '7.5625' to each side of the equation.
5.5x + 7.5625 + x2 = 6 + 7.5625
