(5w+2)(w+3)=0

Solution for (5w+2)(w+3)=0 equation:

Simplifying
(5w + 2)(w + 3) = 0

Reorder the terms:
(2 + 5w)(w + 3) = 0

Reorder the terms:
(2 + 5w)(3 + w) = 0

Multiply (2 + 5w) * (3 + w)
(2(3 + w) + 5w * (3 + w)) = 0
((3 * 2 + w * 2) + 5w * (3 + w)) = 0
((6 + 2w) + 5w * (3 + w)) = 0
(6 + 2w + (3 * 5w + w * 5w)) = 0
(6 + 2w + (15w + 5w2)) = 0

Combine like terms: 2w + 15w = 17w
(6 + 17w + 5w2) = 0

Solving
6 + 17w + 5w2 = 0

Subproblem 1
Set the factor '(3 + w)' equal to zero and attempt to solve:

Simplifying
3 + w = 0

Solving
3 + w = 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 + w = 0 + -3

Combine like terms: 3 + -3 = 0
0 + w = 0 + -3
w = 0 + -3

Combine like terms: 0 + -3 = -3
w = -3

Simplifying
w = -3
Subproblem 2
Set the factor '(2 + 5w)' equal to zero and attempt to solve:

Simplifying
2 + 5w = 0

Solving
2 + 5w = 0

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

Add '-2' to each side of the equation.
2 + -2 + 5w = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 5w = 0 + -2
5w = 0 + -2

Combine like terms: 0 + -2 = -2
5w = -2

Divide each side by '5'.
w = -0.4

Simplifying
w = -0.4
Solution
w = {-3, -0.4}
