Solution for w(w+4)=(w+3)(w+4) equation:


Simplifying
w(w + 4) = (w + 3)(w + 4)

Reorder the terms:
w(4 + w) = (w + 3)(w + 4)
(4 * w + w * w) = (w + 3)(w + 4)
(4w + w2) = (w + 3)(w + 4)

Reorder the terms:
4w + w2 = (3 + w)(w + 4)

Reorder the terms:
4w + w2 = (3 + w)(4 + w)

Multiply (3 + w) * (4 + w)
4w + w2 = (3(4 + w) + w(4 + w))
4w + w2 = ((4 * 3 + w * 3) + w(4 + w))
4w + w2 = ((12 + 3w) + w(4 + w))
4w + w2 = (12 + 3w + (4 * w + w * w))
4w + w2 = (12 + 3w + (4w + w2))

Combine like terms: 3w + 4w = 7w
4w + w2 = (12 + 7w + w2)

Add '-1w2' to each side of the equation.
4w + w2 + -1w2 = 12 + 7w + w2 + -1w2

Combine like terms: w2 + -1w2 = 0
4w + 0 = 12 + 7w + w2 + -1w2
4w = 12 + 7w + w2 + -1w2

Combine like terms: w2 + -1w2 = 0
4w = 12 + 7w + 0
4w = 12 + 7w

Solving
4w = 12 + 7w

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '-7w' to each side of the equation.
4w + -7w = 12 + 7w + -7w

Combine like terms: 4w + -7w = -3w
-3w = 12 + 7w + -7w

Combine like terms: 7w + -7w = 0
-3w = 12 + 0
-3w = 12

Divide each side by '-3'.
w = -4

Simplifying
w = -4
