Solution for 80=(2w+6)w equation:


Simplifying
80 = (2w + 6) * w

Reorder the terms:
80 = (6 + 2w) * w

Reorder the terms for easier multiplication:
80 = w(6 + 2w)
80 = (6 * w + 2w * w)
80 = (6w + 2w2)

Solving
80 = 6w + 2w2

Solving for variable 'w'.

Reorder the terms:
80 + -6w + -2w2 = 6w + -6w + 2w2 + -2w2

Combine like terms: 6w + -6w = 0
80 + -6w + -2w2 = 0 + 2w2 + -2w2
80 + -6w + -2w2 = 2w2 + -2w2

Combine like terms: 2w2 + -2w2 = 0
80 + -6w + -2w2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(40 + -3w + -1w2) = 0

Factor a trinomial.
2((5 + -1w)(8 + w)) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(5 + -1w)' equal to zero and attempt to solve: Simplifying 5 + -1w = 0 Solving 5 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1w = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1w = 0 + -5 -1w = 0 + -5 Combine like terms: 0 + -5 = -5 -1w = -5 Divide each side by '-1'. w = 5 Simplifying w = 5

Subproblem 2

Set the factor '(8 + w)' equal to zero and attempt to solve: Simplifying 8 + w = 0 Solving 8 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + w = 0 + -8 Combine like terms: 8 + -8 = 0 0 + w = 0 + -8 w = 0 + -8 Combine like terms: 0 + -8 = -8 w = -8 Simplifying w = -8

Solution

w = {5, -8}
