Solution for (w+4)(w+5)= equation:


Simplifying
(w + 4)(w + 5) = 0

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

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

Multiply (4 + w) * (5 + w)
(4(5 + w) + w(5 + w)) = 0
((5 * 4 + w * 4) + w(5 + w)) = 0
((20 + 4w) + w(5 + w)) = 0
(20 + 4w + (5 * w + w * w)) = 0
(20 + 4w + (5w + w2)) = 0

Combine like terms: 4w + 5w = 9w
(20 + 9w + w2) = 0

Solving
20 + 9w + w2 = 0
