(x + 4)(x + 15) = 6x

Reorder the terms:
(4 + x)(x + 15) = 6x

Reorder the terms:
(4 + x)(15 + x) = 6x

Multiply (4 + x) * (15 + x)
(4(15 + x) + x(15 + x)) = 6x
((15 * 4 + x * 4) + x(15 + x)) = 6x
((60 + 4x) + x(15 + x)) = 6x
(60 + 4x + (15 * x + x * x)) = 6x
(60 + 4x + (15x + x2)) = 6x

Combine like terms: 4x + 15x = 19x
(60 + 19x + x2) = 6x

Solving
60 + 19x + x2 = 6x

Solving for variable 'x'.

Reorder the terms:
60 + 19x + -6x + x2 = 6x + -6x

Combine like terms: 19x + -6x = 13x
60 + 13x + x2 = 6x + -6x

Combine like terms: 6x + -6x = 0
60 + 13x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-60' to each side of the equation.
60 + 13x + -60 + x2 = 0 + -60

Reorder the terms:
60 + -60 + 13x + x2 = 0 + -60

Combine like terms: 60 + -60 = 0
0 + 13x + x2 = 0 + -60
13x + x2 = 0 + -60
