Solution for (g+9)(g-2)= equation:


Simplifying
(g + 9)(g + -2) = 0

Reorder the terms:
(9 + g)(g + -2) = 0

Reorder the terms:
(9 + g)(-2 + g) = 0

Multiply (9 + g) * (-2 + g)
(9(-2 + g) + g(-2 + g)) = 0
((-2 * 9 + g * 9) + g(-2 + g)) = 0
((-18 + 9g) + g(-2 + g)) = 0
(-18 + 9g + (-2 * g + g * g)) = 0
(-18 + 9g + (-2g + g2)) = 0

Combine like terms: 9g + -2g = 7g
(-18 + 7g + g2) = 0

Solving
-18 + 7g + g2 = 0

Solving for variable 'g'.

Factor a trinomial.
