Solution for (8+w)(4+w)=252 equation:


Simplifying
(8 + w)(4 + w) = 252

Multiply (8 + w) * (4 + w)
(8(4 + w) + w(4 + w)) = 252
((4 * 8 + w * 8) + w(4 + w)) = 252
((32 + 8w) + w(4 + w)) = 252
(32 + 8w + (4 * w + w * w)) = 252
(32 + 8w + (4w + w2)) = 252

Combine like terms: 8w + 4w = 12w
(32 + 12w + w2) = 252

Solving
32 + 12w + w2 = 252

Solving for variable 'w'.

Reorder the terms:
32 + -252 + 12w + w2 = 252 + -252
