Solution for (w^2+w-1)(w^2+7w-9)= equation:


Simplifying
(w2 + w + -1)(w2 + 7w + -9) = 0

Reorder the terms:
(-1 + w + w2)(w2 + 7w + -9) = 0

Reorder the terms:
(-1 + w + w2)(-9 + 7w + w2) = 0

Multiply (-1 + w + w2) * (-9 + 7w + w2)
(-1(-9 + 7w + w2) + w(-9 + 7w + w2) + w2(-9 + 7w + w2)) = 0
((-9 * -1 + 7w * -1 + w2 * -1) + w(-9 + 7w + w2) + w2(-9 + 7w + w2)) = 0
((9 + -7w + -1w2) + w(-9 + 7w + w2) + w2(-9 + 7w + w2)) = 0
(9 + -7w + -1w2 + (-9 * w + 7w * w + w2 * w) + w2(-9 + 7w + w2)) = 0
(9 + -7w + -1w2 + (-9w + 7w2 + w3) + w2(-9 + 7w + w2)) = 0
(9 + -7w + -1w2 + -9w + 7w2 + w3 + (-9 * w2 + 7w * w2 + w2 * w2)) = 0
(9 + -7w + -1w2 + -9w + 7w2 + w3 + (-9w2 + 7w3 + w4)) = 0

Reorder the terms:
(9 + -7w + -9w + -1w2 + 7w2 + -9w2 + w3 + 7w3 + w4) = 0

Combine like terms: -7w + -9w = -16w
(9 + -16w + -1w2 + 7w2 + -9w2 + w3 + 7w3 + w4) = 0

Combine like terms: -1w2 + 7w2 = 6w2
(9 + -16w + 6w2 + -9w2 + w3 + 7w3 + w4) = 0

Combine like terms: 6w2 + -9w2 = -3w2
(9 + -16w + -3w2 + w3 + 7w3 + w4) = 0

Combine like terms: w3 + 7w3 = 8w3
(9 + -16w + -3w2 + 8w3 + w4) = 0

Solving
9 + -16w + -3w2 + 8w3 + w4 = 0

Solving for variable 'w'.
