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

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

Simplifying
(2 + -1w)(5w + 3) = 0

Reorder the terms:
(2 + -1w)(3 + 5w) = 0

Multiply (2 + -1w) * (3 + 5w)
(2(3 + 5w) + -1w * (3 + 5w)) = 0
((3 * 2 + 5w * 2) + -1w * (3 + 5w)) = 0
((6 + 10w) + -1w * (3 + 5w)) = 0
(6 + 10w + (3 * -1w + 5w * -1w)) = 0
(6 + 10w + (-3w + -5w2)) = 0

Combine like terms: 10w + -3w = 7w
(6 + 7w + -5w2) = 0

Solving
6 + 7w + -5w2 = 0

Solving for variable 'w'.
