(2w+7)(1+w)=0

Solution for (2w+7)(1+w)=0 equation:

Simplifying
(2w + 7)(1 + w) = 0

Reorder the terms:
(7 + 2w)(1 + w) = 0

Multiply (7 + 2w) * (1 + w)
(7(1 + w) + 2w * (1 + w)) = 0
((1 * 7 + w * 7) + 2w * (1 + w)) = 0
((7 + 7w) + 2w * (1 + w)) = 0
(7 + 7w + (1 * 2w + w * 2w)) = 0
(7 + 7w + (2w + 2w2)) = 0

Combine like terms: 7w + 2w = 9w
(7 + 9w + 2w2) = 0

Solving
7 + 9w + 2w2 = 0

Solving for variable 'w'.

Factor a trinomial.

w = -3.5

Simplifying
w = -3.5
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 = {-3.5, -1}
