Solution for (w+4)(w+9)-(w)(w+5)=76 equation:


Simplifying
(w + 4)(w + 9) + -1(w)(w + 5) = 76

Reorder the terms:
(4 + w)(w + 9) + -1(w)(w + 5) = 76

Reorder the terms:
(4 + w)(9 + w) + -1(w)(w + 5) = 76

Multiply (4 + w) * (9 + w)
(4(9 + w) + w(9 + w)) + -1(w)(w + 5) = 76
((9 * 4 + w * 4) + w(9 + w)) + -1(w)(w + 5) = 76
((36 + 4w) + w(9 + w)) + -1(w)(w + 5) = 76
(36 + 4w + (9 * w + w * w)) + -1(w)(w + 5) = 76
(36 + 4w + (9w + w2)) + -1(w)(w + 5) = 76

Combine like terms: 4w + 9w = 13w
(36 + 13w + w2) + -1(w)(w + 5) = 76

Reorder the terms:
36 + 13w + w2 + -1w(5 + w) = 76
36 + 13w + w2 + (5 * -1w + w * -1w) = 76
36 + 13w + w2 + (-5w + -1w2) = 76

Reorder the terms:
36 + 13w + -5w + w2 + -1w2 = 76

Combine like terms: 13w + -5w = 8w
36 + 8w + w2 + -1w2 = 76

Combine like terms: w2 + -1w2 = 0
36 + 8w + 0 = 76
36 + 8w = 76
