Solution for (x+4)(x+4)=x equation:


Simplifying
(x + 4)(x + 4) = x

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

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

Multiply (4 + x) * (4 + x)
(4(4 + x) + x(4 + x)) = x
((4 * 4 + x * 4) + x(4 + x)) = x
((16 + 4x) + x(4 + x)) = x
(16 + 4x + (4 * x + x * x)) = x
(16 + 4x + (4x + x2)) = x

Combine like terms: 4x + 4x = 8x
(16 + 8x + x2) = x

Solving
16 + 8x + x2 = x

Solving for variable 'x'.

Reorder the terms:
16 + 8x + -1x + x2 = x + -1x

Combine like terms: 8x + -1x = 7x
16 + 7x + x2 = x + -1x

Combine like terms: x + -1x = 0
16 + 7x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-16' to each side of the equation.
16 + 7x + -16 + x2 = 0 + -16

Reorder the terms:
16 + -16 + 7x + x2 = 0 + -16

Combine like terms: 16 + -16 = 0
0 + 7x + x2 = 0 + -16
7x + x2 = 0 + -16

Combine like terms: 0 + -16 = -16
7x + x2 = -16

The x term is 7x.  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
7x + 12.25 + x2 = -16 + 12.25

Reorder the terms:
12.25 + 7x + x2 = -16 + 12.25

Combine like terms: -16 + 12.25 = -3.75
12.25 + 7x + x2 = -3.75

Factor a perfect square on the left side:
(x + 3.5)(x + 3.5) = -3.75

Can't calculate square root of the right side.
