Solution for (w+2)(w+11)=-18 equation:


Simplifying
(w + 2)(w + 11) = -18

Reorder the terms:
(2 + w)(w + 11) = -18

Reorder the terms:
(2 + w)(11 + w) = -18

Multiply (2 + w) * (11 + w)
(2(11 + w) + w(11 + w)) = -18
((11 * 2 + w * 2) + w(11 + w)) = -18
((22 + 2w) + w(11 + w)) = -18
(22 + 2w + (11 * w + w * w)) = -18
(22 + 2w + (11w + w2)) = -18

Combine like terms: 2w + 11w = 13w
(22 + 13w + w2) = -18

Solving
22 + 13w + w2 = -18

Solving for variable 'w'.

Reorder the terms:
22 + 18 + 13w + w2 = -18 + 18
