(w+5)*(w-3)=0

Solution for (w+5)*(w-3)=0 equation:

Simplifying
(w + 5)(w + -3) = 0

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

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

Multiply (5 + w) * (-3 + w)
(5(-3 + w) + w(-3 + w)) = 0
((-3 * 5 + w * 5) + w(-3 + w)) = 0
((-15 + 5w) + w(-3 + w)) = 0
(-15 + 5w + (-3 * w + w * w)) = 0
(-15 + 5w + (-3w + w2)) = 0

Combine like terms: 5w + -3w = 2w
(-15 + 2w + w2) = 0

Solving
-15 + 2w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-5 + -1w)(3 + -1w) = 0

Subproblem 1
Set the factor '(-5 + -1w)' equal to zero and attempt to solve:

Simplifying
-5 + -1w = 0

Solving
-5 + -1w = 0

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

Add '5' to each side of the equation.
-5 + 5 + -1w = 0 + 5

Combine like terms: -5 + 5 = 0
0 + -1w = 0 + 5
-1w = 0 + 5

Combine like terms: 0 + 5 = 5
-1w = 5

Divide each side by '-1'.
w = -5

Simplifying
w = -5
Subproblem 2
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
Solution
w = {-5, 3}
