Solution for (w-9)*(w-4)= equation:


Simplifying
(w + -9)(w + -4) = 0

Reorder the terms:
(-9 + w)(w + -4) = 0

Reorder the terms:
(-9 + w)(-4 + w) = 0

Multiply (-9 + w) * (-4 + w)
(-9(-4 + w) + w(-4 + w)) = 0
((-4 * -9 + w * -9) + w(-4 + w)) = 0
((36 + -9w) + w(-4 + w)) = 0
(36 + -9w + (-4 * w + w * w)) = 0
(36 + -9w + (-4w + w2)) = 0

Combine like terms: -9w + -4w = -13w
(36 + -13w + w2) = 0

Solving
36 + -13w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.

Subproblem 1

Set the factor '(4 + -1w)' equal to zero and attempt to solve: Simplifying 4 + -1w = 0 Solving 4 + -1w = 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 + -1w = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1w = 0 + -4 -1w = 0 + -4 Combine like terms: 0 + -4 = -4 -1w = -4 Divide each side by '-1'. w = 4 Simplifying w = 4

Subproblem 2

Set the factor '(9 + -1w)' equal to zero and attempt to solve: Simplifying 9 + -1w = 0 Solving 9 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1w = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1w = 0 + -9 -1w = 0 + -9 Combine like terms: 0 + -9 = -9 -1w = -9 Divide each side by '-1'. w = 9 Simplifying w = 9

Solution

w = {4, 9}
