Solution for (w+5)*(w^2+3w)= equation:


Simplifying
(w + 5)(w2 + 3w) = 0

Reorder the terms:
(5 + w)(w2 + 3w) = 0

Reorder the terms:
(5 + w)(3w + w2) = 0

Multiply (5 + w) * (3w + w2)
(5(3w + w2) + w(3w + w2)) = 0
((3w * 5 + w2 * 5) + w(3w + w2)) = 0
((15w + 5w2) + w(3w + w2)) = 0
(15w + 5w2 + (3w * w + w2 * w)) = 0
(15w + 5w2 + (3w2 + w3)) = 0

Combine like terms: 5w2 + 3w2 = 8w2
(15w + 8w2 + w3) = 0

Solving
15w + 8w2 + w3 = 0
