Solution for 5=-2(w+2)(w+5)-5(w+2) equation:


Simplifying
5 = -2(w + 2)(w + 5) + -5(w + 2)

Reorder the terms:
5 = -2(2 + w)(w + 5) + -5(w + 2)

Reorder the terms:
5 = -2(2 + w)(5 + w) + -5(w + 2)

Multiply (2 + w) * (5 + w)
5 = -2(2(5 + w) + w(5 + w)) + -5(w + 2)
5 = -2((5 * 2 + w * 2) + w(5 + w)) + -5(w + 2)
5 = -2((10 + 2w) + w(5 + w)) + -5(w + 2)
5 = -2(10 + 2w + (5 * w + w * w)) + -5(w + 2)
5 = -2(10 + 2w + (5w + w2)) + -5(w + 2)

Combine like terms: 2w + 5w = 7w
5 = -2(10 + 7w + w2) + -5(w + 2)
5 = (10 * -2 + 7w * -2 + w2 * -2) + -5(w + 2)
5 = (-20 + -14w + -2w2) + -5(w + 2)

Reorder the terms:
5 = -20 + -14w + -2w2 + -5(2 + w)
5 = -20 + -14w + -2w2 + (2 * -5 + w * -5)
5 = -20 + -14w + -2w2 + (-10 + -5w)

Reorder the terms:
5 = -20 + -10 + -14w + -5w + -2w2

Combine like terms: -20 + -10 = -30
5 = -30 + -14w + -5w + -2w2

Combine like terms: -14w + -5w = -19w
5 = -30 + -19w + -2w2

Solving
5 = -30 + -19w + -2w2

Solving for variable 'w'.

Combine like terms: 5 + 30 = 35
35 + 19w + 2w2 = -30 + -19w + -2w2 + 30 + 19w + 2w2

Reorder the terms:
35 + 19w + 2w2 = -30 + 30 + -19w + 19w + -2w2 + 2w2

Combine like terms: -30 + 30 = 0
35 + 19w + 2w2 = 0 + -19w + 19w + -2w2 + 2w2
35 + 19w + 2w2 = -19w + 19w + -2w2 + 2w2

Combine like terms: -19w + 19w = 0
35 + 19w + 2w2 = 0 + -2w2 + 2w2
35 + 19w + 2w2 = -2w2 + 2w2

Combine like terms: -2w2 + 2w2 = 0
35 + 19w + 2w2 = 0
