(w+3)(w-1)=0

Solution for (w+3)(w-1)=0 equation:

Simplifying
(w + 3)(w + -1) = 0

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

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

Multiply (3 + w) * (-1 + w)
(3(-1 + w) + w(-1 + w)) = 0
((-1 * 3 + w * 3) + w(-1 + w)) = 0
((-3 + 3w) + w(-1 + w)) = 0
(-3 + 3w + (-1 * w + w * w)) = 0
(-3 + 3w + (-1w + w2)) = 0

Combine like terms: 3w + -1w = 2w
(-3 + 2w + w2) = 0

Solving
-3 + 2w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-3 + -1w)(1 + -1w) = 0

Subproblem 1
Set the factor '(-3 + -1w)' equal to zero and attempt to solve:

Simplifying
-3 + -1w = 0

Solving
-3 + -1w = 0

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

Add '3' to each side of the equation.
-3 + 3 + -1w = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -1w = 0 + 3
-1w = 0 + 3

Combine like terms: 0 + 3 = 3
-1w = 3

Divide each side by '-1'.
w = -3

Simplifying
w = -3
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 = {-3, 1}
