Solution for w(w+3)=w(7-w) equation:


Simplifying
w(w + 3) = w(7 + -1w)

Reorder the terms:
w(3 + w) = w(7 + -1w)
(3 * w + w * w) = w(7 + -1w)
(3w + w2) = w(7 + -1w)
3w + w2 = (7 * w + -1w * w)
3w + w2 = (7w + -1w2)

Solving
3w + w2 = 7w + -1w2

Solving for variable 'w'.

Reorder the terms:
3w + -7w + w2 + w2 = 7w + -1w2 + -7w + w2

Combine like terms: 3w + -7w = -4w
-4w + w2 + w2 = 7w + -1w2 + -7w + w2

Combine like terms: w2 + w2 = 2w2
-4w + 2w2 = 7w + -1w2 + -7w + w2

Reorder the terms:
-4w + 2w2 = 7w + -7w + -1w2 + w2

Combine like terms: 7w + -7w = 0
-4w + 2w2 = 0 + -1w2 + w2
-4w + 2w2 = -1w2 + w2

Combine like terms: -1w2 + w2 = 0
-4w + 2w2 = 0

Factor out the Greatest Common Factor (GCF), '2w'.
2w(-2 + w) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'w' equal to zero and attempt to solve: Simplifying w = 0 Solving w = 0 Move all terms containing w to the left, all other terms to the right. Simplifying w = 0

Subproblem 2

Set the factor '(-2 + w)' equal to zero and attempt to solve: Simplifying -2 + w = 0 Solving -2 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + w = 0 + 2 Combine like terms: -2 + 2 = 0 0 + w = 0 + 2 w = 0 + 2 Combine like terms: 0 + 2 = 2 w = 2 Simplifying w = 2

Solution

w = {0, 2}
