Solution for 1600=w(60+w) equation:


Simplifying
1600 = w(60 + w)
1600 = (60 * w + w * w)
1600 = (60w + w2)

Solving
1600 = 60w + w2

Solving for variable 'w'.

Reorder the terms:
1600 + -60w + -1w2 = 60w + -60w + w2 + -1w2

Combine like terms: 60w + -60w = 0
1600 + -60w + -1w2 = 0 + w2 + -1w2
1600 + -60w + -1w2 = w2 + -1w2

Combine like terms: w2 + -1w2 = 0
1600 + -60w + -1w2 = 0

Factor a trinomial.
(20 + -1w)(80 + w) = 0

Subproblem 1

Set the factor '(20 + -1w)' equal to zero and attempt to solve: Simplifying 20 + -1w = 0 Solving 20 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + -1w = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -1w = 0 + -20 -1w = 0 + -20 Combine like terms: 0 + -20 = -20 -1w = -20 Divide each side by '-1'. w = 20 Simplifying w = 20

Subproblem 2

Set the factor '(80 + w)' equal to zero and attempt to solve: Simplifying 80 + w = 0 Solving 80 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-80' to each side of the equation. 80 + -80 + w = 0 + -80 Combine like terms: 80 + -80 = 0 0 + w = 0 + -80 w = 0 + -80 Combine like terms: 0 + -80 = -80 w = -80 Simplifying w = -80

Solution

w = {20, -80}
