(3+w)(5w-1)=0

Solution for (3+w)(5w-1)=0 equation:

Simplifying
(3 + w)(5w + -1) = 0

Reorder the terms:
(3 + w)(-1 + 5w) = 0

Multiply (3 + w) * (-1 + 5w)
(3(-1 + 5w) + w(-1 + 5w)) = 0
((-1 * 3 + 5w * 3) + w(-1 + 5w)) = 0
((-3 + 15w) + w(-1 + 5w)) = 0
(-3 + 15w + (-1 * w + 5w * w)) = 0
(-3 + 15w + (-1w + 5w2)) = 0

Combine like terms: 15w + -1w = 14w
(-3 + 14w + 5w2) = 0

Solving
-3 + 14w + 5w2 = 0

Solving for variable 'w'.

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

Subproblem 1
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
Subproblem 2
Set the factor '(1 + -5w)' equal to zero and attempt to solve:

Simplifying
1 + -5w = 0

Solving
1 + -5w = 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 + -5w = 0 + -1

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

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

Divide each side by '-5'.
w = 0.2

Simplifying
w = 0.2
Solution
w = {-3, 0.2}
