Multiply (3 + 10w) * (-2 + w)
-16 + 6w + w2 + (3(-2 + w) + 10w * (-2 + w)) = 0
-16 + 6w + w2 + ((-2 * 3 + w * 3) + 10w * (-2 + w)) = 0
-16 + 6w + w2 + ((-6 + 3w) + 10w * (-2 + w)) = 0
-16 + 6w + w2 + (-6 + 3w + (-2 * 10w + w * 10w)) = 0
-16 + 6w + w2 + (-6 + 3w + (-20w + 10w2)) = 0

Combine like terms: 3w + -20w = -17w
-16 + 6w + w2 + (-6 + -17w + 10w2) = 0

Reorder the terms:
-16 + -6 + 6w + -17w + w2 + 10w2 = 0

Combine like terms: -16 + -6 = -22
-22 + 6w + -17w + w2 + 10w2 = 0

Combine like terms: 6w + -17w = -11w
-22 + -11w + w2 + 10w2 = 0

Combine like terms: w2 + 10w2 = 11w2
-22 + -11w + 11w2 = 0

Solving
-22 + -11w + 11w2 = 0

Solving for variable 'w'.

Factor out the Greatest Common Factor (GCF), '11'.
11(-2 + -1w + w2) = 0

Ignore the factor 11.

Subproblem 1

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

Subproblem 2

Set the factor '(2 + -1w)' equal to zero and attempt to solve: Simplifying 2 + -1w = 0 Solving 2 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1w = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1w = 0 + -2 -1w = 0 + -2 Combine like terms: 0 + -2 = -2 -1w = -2 Divide each side by '-1'. w = 2 Simplifying w = 2

Solution

w = {-1, 2}
