Solution for (w+7)(w-4)=x equation:


Simplifying
(w + 7)(w + -4) = x

Reorder the terms:
(7 + w)(w + -4) = x

Reorder the terms:
(7 + w)(-4 + w) = x

Multiply (7 + w) * (-4 + w)
(7(-4 + w) + w(-4 + w)) = x
((-4 * 7 + w * 7) + w(-4 + w)) = x
((-28 + 7w) + w(-4 + w)) = x
(-28 + 7w + (-4 * w + w * w)) = x
(-28 + 7w + (-4w + w2)) = x

Combine like terms: 7w + -4w = 3w
(-28 + 3w + w2) = x

Solving
-28 + 3w + w2 = x

Solving for variable 'w'.

Combine like terms: x + -1x = 0
