Solution for 80=2w+w*w equation:


Simplifying
80 = 2w + w * w

Multiply w * w
80 = 2w + w2

Solving
80 = 2w + w2

Solving for variable 'w'.

Reorder the terms:
80 + -2w + -1w2 = 2w + -2w + w2 + -1w2

Combine like terms: 2w + -2w = 0
80 + -2w + -1w2 = 0 + w2 + -1w2
80 + -2w + -1w2 = w2 + -1w2

Combine like terms: w2 + -1w2 = 0
80 + -2w + -1w2 = 0

Factor a trinomial.
(8 + -1w)(10 + w) = 0

Subproblem 1

Set the factor '(8 + -1w)' equal to zero and attempt to solve: Simplifying 8 + -1w = 0 Solving 8 + -1w = 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 + -1w = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1w = 0 + -8 -1w = 0 + -8 Combine like terms: 0 + -8 = -8 -1w = -8 Divide each side by '-1'. w = 8 Simplifying w = 8

Subproblem 2

Set the factor '(10 + w)' equal to zero and attempt to solve: Simplifying 10 + w = 0 Solving 10 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + w = 0 + -10 Combine like terms: 10 + -10 = 0 0 + w = 0 + -10 w = 0 + -10 Combine like terms: 0 + -10 = -10 w = -10 Simplifying w = -10

Solution

w = {8, -10}
