Solution for 2w(w-1)=w(w+2) equation:


Simplifying
2w(w + -1) = w(w + 2)

Reorder the terms:
2w(-1 + w) = w(w + 2)
(-1 * 2w + w * 2w) = w(w + 2)
(-2w + 2w2) = w(w + 2)

Reorder the terms:
-2w + 2w2 = w(2 + w)
-2w + 2w2 = (2 * w + w * w)
-2w + 2w2 = (2w + w2)

Solving
-2w + 2w2 = 2w + w2

Solving for variable 'w'.

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

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

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

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

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

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

Factor out the Greatest Common Factor (GCF), 'w'.
w(-4 + w) = 0

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 '(-4 + w)' equal to zero and attempt to solve: Simplifying -4 + w = 0 Solving -4 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + w = 0 + 4 Combine like terms: -4 + 4 = 0 0 + w = 0 + 4 w = 0 + 4 Combine like terms: 0 + 4 = 4 w = 4 Simplifying w = 4

Solution

w = {0, 4}
