Answer:
2g2 - 9g - 1
Step-by-step explanation:
(2g2 - 9g) - 1
2.1 Factoring 2g2-9g-1
The first term is, 2g2 its coefficient is 2 .
The middle term is, -9g its coefficient is -9 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2
Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -9 .
2 + 1 = -1
-1 + 2 = 1
