(w-4)(w+3)=0

Solution for (w-4)(w+3)=0 equation:

Simplifying
(w + -4)(w + 3) = 0

Reorder the terms:
(-4 + w)(w + 3) = 0

Reorder the terms:
(-4 + w)(3 + w) = 0

Multiply (-4 + w) * (3 + w)
(-4(3 + w) + w(3 + w)) = 0
((3 * -4 + w * -4) + w(3 + w)) = 0
((-12 + -4w) + w(3 + w)) = 0
(-12 + -4w + (3 * w + w * w)) = 0
(-12 + -4w + (3w + w2)) = 0

Combine like terms: -4w + 3w = -1w
(-12 + -1w + w2) = 0

Solving
-12 + -1w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-3 + -1w)(4 + -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 '(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
Solution
w = {-3, 4}
