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


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

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

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

Multiply (-5 + 2w) * (2 + w)
(-5(2 + w) + 2w * (2 + w)) = 0
((2 * -5 + w * -5) + 2w * (2 + w)) = 0
((-10 + -5w) + 2w * (2 + w)) = 0
(-10 + -5w + (2 * 2w + w * 2w)) = 0
(-10 + -5w + (4w + 2w2)) = 0

Combine like terms: -5w + 4w = -1w
(-10 + -1w + 2w2) = 0
