Solution for (g+3)(g-9)=0 equation:


Simplifying
(g + 3)(g + -9) = 0

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

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

Multiply (3 + g) * (-9 + g)
(3(-9 + g) + g(-9 + g)) = 0
((-9 * 3 + g * 3) + g(-9 + g)) = 0
((-27 + 3g) + g(-9 + g)) = 0
(-27 + 3g + (-9 * g + g * g)) = 0
(-27 + 3g + (-9g + g2)) = 0

Combine like terms: 3g + -9g = -6g
(-27 + -6g + g2) = 0

Solving
-27 + -6g + g2 = 0

Solving for variable 'g'.

Factor a trinomial.
