Solution for (g+7)(g-1)=0 equation:


Simplifying
(g + 7)(g + -1) = 0

Reorder the terms:
(7 + g)(g + -1) = 0

Reorder the terms:
(7 + g)(-1 + g) = 0

Multiply (7 + g) * (-1 + g)
(7(-1 + g) + g(-1 + g)) = 0
((-1 * 7 + g * 7) + g(-1 + g)) = 0
((-7 + 7g) + g(-1 + g)) = 0
(-7 + 7g + (-1 * g + g * g)) = 0
(-7 + 7g + (-1g + g2)) = 0

Combine like terms: 7g + -1g = 6g
(-7 + 6g + g2) = 0

Solving
-7 + 6g + g2 = 0

Solving for variable 'g'.
