(w+4)(w+1)=0

Solution for (w+4)(w+1)=0 equation:

Simplifying
(w + 4)(w + 1) = 0

Reorder the terms:
(4 + w)(w + 1) = 0

Reorder the terms:
(4 + w)(1 + w) = 0

Multiply (4 + w) * (1 + w)
(4(1 + w) + w(1 + w)) = 0
((1 * 4 + w * 4) + w(1 + w)) = 0
((4 + 4w) + w(1 + w)) = 0
(4 + 4w + (1 * w + w * w)) = 0
(4 + 4w + (1w + w2)) = 0

Combine like terms: 4w + 1w = 5w
(4 + 5w + w2) = 0

Solving
4 + 5w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(4 + w)(1 + w) = 0

Subproblem 1
Set the factor '(4 + w)' equal to zero and attempt to solve:

Simplifying
4 + w = 0

Solving
4 + w = 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 + w = 0 + -4

Combine like terms: 4 + -4 = 0
0 + w = 0 + -4
w = 0 + -4

Combine like terms: 0 + -4 = -4
w = -4

Simplifying
w = -4
Subproblem 2
Set the factor '(1 + w)' equal to zero and attempt to solve:

Simplifying
1 + w = 0

Solving
1 + w = 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 + w = 0 + -1

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

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

Simplifying
w = -1
Solution
w = {-4, -1}
