(3w+8)(1+w)=0

Solution for (3w+8)(1+w)=0 equation:

Simplifying
(3w + 8)(1 + w) = 0

Reorder the terms:
(8 + 3w)(1 + w) = 0

Multiply (8 + 3w) * (1 + w)
(8(1 + w) + 3w * (1 + w)) = 0
((1 * 8 + w * 8) + 3w * (1 + w)) = 0
((8 + 8w) + 3w * (1 + w)) = 0
(8 + 8w + (1 * 3w + w * 3w)) = 0
(8 + 8w + (3w + 3w2)) = 0

Combine like terms: 8w + 3w = 11w
(8 + 11w + 3w2) = 0

Solving
8 + 11w + 3w2 = 0

Solving for variable 'w'.

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 = {-2.666666667, -1}
