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

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

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

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

Multiply (3 + -1w) * (1 + 3w)
(3(1 + 3w) + -1w * (1 + 3w)) = 0
((1 * 3 + 3w * 3) + -1w * (1 + 3w)) = 0
((3 + 9w) + -1w * (1 + 3w)) = 0
(3 + 9w + (1 * -1w + 3w * -1w)) = 0
(3 + 9w + (-1w + -3w2)) = 0

Combine like terms: 9w + -1w = 8w
(3 + 8w + -3w2) = 0

Solving
3 + 8w + -3w2 = 0

Solving for variable 'w'.

Factor a trinomial.

w = 3

Simplifying
w = 3
Subproblem 2
Set the factor '(1 + 3w)' equal to zero and attempt to solve:

Simplifying
1 + 3w = 0

Solving
1 + 3w = 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 + 3w = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 3w = 0 + -1
3w = 0 + -1

Combine like terms: 0 + -1 = -1
3w = -1

Divide each side by '3'.
w = -0.3333333333

Simplifying
w = -0.3333333333
Solution
w = {3, -0.3333333333}
