Solution for -4w(w+1)(w+9)=0 equation:


Simplifying
-4w(w + 1)(w + 9) = 0

Reorder the terms:
-4w(1 + w)(w + 9) = 0

Reorder the terms:
-4w(1 + w)(9 + w) = 0

Multiply (1 + w) * (9 + w)
-4w(1(9 + w) + w(9 + w)) = 0
-4w((9 * 1 + w * 1) + w(9 + w)) = 0
-4w((9 + 1w) + w(9 + w)) = 0
-4w(9 + 1w + (9 * w + w * w)) = 0
-4w(9 + 1w + (9w + w2)) = 0

Combine like terms: 1w + 9w = 10w
-4w(9 + 10w + w2) = 0
(9 * -4w + 10w * -4w + w2 * -4w) = 0
(-36w + -40w2 + -4w3) = 0

Solving
-36w + -40w2 + -4w3 = 0

Solving for variable 'w'.

Factor out the Greatest Common Factor (GCF), '-4w'.
