Solution for (W+9)(W+4)-[w(w+5)]=100 equation:


Simplifying
(W + 9)(W + 4) + -1[w(w + 5)] = 100

Reorder the terms:
(9 + W)(W + 4) + -1[w(w + 5)] = 100

Reorder the terms:
(9 + W)(4 + W) + -1[w(w + 5)] = 100

Multiply (9 + W) * (4 + W)
(9(4 + W) + W(4 + W)) + -1[w(w + 5)] = 100
((4 * 9 + W * 9) + W(4 + W)) + -1[w(w + 5)] = 100
((36 + 9W) + W(4 + W)) + -1[w(w + 5)] = 100
(36 + 9W + (4 * W + W * W)) + -1[w(w + 5)] = 100
(36 + 9W + (4W + W2)) + -1[w(w + 5)] = 100

Combine like terms: 9W + 4W = 13W
(36 + 13W + W2) + -1[w(w + 5)] = 100

Reorder the terms:
36 + 13W + W2 + -1[w(5 + w)] = 100
36 + 13W + W2 + -1[(5 * w + w * w)] = 100
36 + 13W + W2 + -1[(5w + w2)] = 100
36 + 13W + W2 + [5w * -1 + w2 * -1] = 100
36 + 13W + W2 + [-5w + -1w2] = 100

Solving
36 + 13W + W2 + -5w + -1w2 = 100

Solving for variable 'W'.

Reorder the terms:
36 + -100 + 13W + W2 + -5w + -1w2 = 100 + -100

Combine like terms: 36 + -100 = -64
-64 + 13W + W2 + -5w + -1w2 = 100 + -100

Combine like terms: 100 + -100 = 0
-64 + 13W + W2 + -5w + -1w2 = 0

The solution to this equation could not be determined.
