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

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

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

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

Multiply (-1 + 5w) * (5 + w)
(-1(5 + w) + 5w * (5 + w)) = 0
((5 * -1 + w * -1) + 5w * (5 + w)) = 0
((-5 + -1w) + 5w * (5 + w)) = 0
(-5 + -1w + (5 * 5w + w * 5w)) = 0
(-5 + -1w + (25w + 5w2)) = 0

Combine like terms: -1w + 25w = 24w
(-5 + 24w + 5w2) = 0

Solving
-5 + 24w + 5w2 = 0

Solving for variable 'w'.

Factor a trinomial.

Divide each side by '-1'.
w = -5

Simplifying
w = -5
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 = {-5, 0.2}
