(w-1)(w+2)=

Solution for (w-1)(w+2)= equation:

Simplifying
(w + -1)(w + 2) = 0

Reorder the terms:
(-1 + w)(w + 2) = 0

Reorder the terms:
(-1 + w)(2 + w) = 0

Multiply (-1 + w) * (2 + w)
(-1(2 + w) + w(2 + w)) = 0
((2 * -1 + w * -1) + w(2 + w)) = 0
((-2 + -1w) + w(2 + w)) = 0
(-2 + -1w + (2 * w + w * w)) = 0
(-2 + -1w + (2w + w2)) = 0

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

Solving
-2 + 1w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-2 + -1w)(1 + -1w) = 0

Subproblem 1
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
Subproblem 2
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
Solution
w = {-2, 1}
