(4w-1)(5w+3)=

Solution for (4w-1)(5w+3)= equation:

Simplifying
(4w + -1)(5w + 3) = 0

Reorder the terms:
(-1 + 4w)(5w + 3) = 0

Reorder the terms:
(-1 + 4w)(3 + 5w) = 0

Multiply (-1 + 4w) * (3 + 5w)
(-1(3 + 5w) + 4w * (3 + 5w)) = 0
((3 * -1 + 5w * -1) + 4w * (3 + 5w)) = 0
((-3 + -5w) + 4w * (3 + 5w)) = 0
(-3 + -5w + (3 * 4w + 5w * 4w)) = 0
(-3 + -5w + (12w + 20w2)) = 0

Combine like terms: -5w + 12w = 7w
(-3 + 7w + 20w2) = 0

Solving
-3 + 7w + 20w2 = 0
