(x+4)*(x+4)=0

Solution for (x+4)*(x+4)=0 equation:

Simplifying
(x + 4)(x + 4) = 0

Reorder the terms:
(4 + x)(x + 4) = 0

Reorder the terms:
(4 + x)(4 + x) = 0

Multiply (4 + x) * (4 + x)
(4(4 + x) + x(4 + x)) = 0
((4 * 4 + x * 4) + x(4 + x)) = 0
((16 + 4x) + x(4 + x)) = 0
(16 + 4x + (4 * x + x * x)) = 0
(16 + 4x + (4x + x2)) = 0

Combine like terms: 4x + 4x = 8x
(16 + 8x + x2) = 0

Solving
16 + 8x + x2 = 0
