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


Simplifying
3w = w(7 + -1w)
3w = (7 * w + -1w * w)
3w = (7w + -1w2)

Solving
3w = 7w + -1w2

Solving for variable 'w'.

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

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

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

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