(w+9)*(w-6)=

Solution for (w+9)*(w-6)= equation:

Simplifying
(w + 9)(w + -6) = 0

Reorder the terms:
(9 + w)(w + -6) = 0

Reorder the terms:
(9 + w)(-6 + w) = 0

Multiply (9 + w) * (-6 + w)
(9(-6 + w) + w(-6 + w)) = 0
((-6 * 9 + w * 9) + w(-6 + w)) = 0
((-54 + 9w) + w(-6 + w)) = 0
(-54 + 9w + (-6 * w + w * w)) = 0
(-54 + 9w + (-6w + w2)) = 0

Combine like terms: 9w + -6w = 3w
(-54 + 3w + w2) = 0

Solving
-54 + 3w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-9 + -1w)(6 + -1w) = 0

Subproblem 1
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
Subproblem 2
Set the factor '(6 + -1w)' equal to zero and attempt to solve:

Simplifying
6 + -1w = 0

Solving
6 + -1w = 0

Move all terms containing w to the left, all other terms to the right.

Add '-6' to each side of the equation.
6 + -6 + -1w = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1w = 0 + -6
-1w = 0 + -6

Combine like terms: 0 + -6 = -6
-1w = -6

Divide each side by '-1'.
w = 6

Simplifying
w = 6
Solution
w = {-9, 6}
