Answer:
9x
Step-by-step explanation:
-4.5X(-2)
-4.5x * -2
9x
3.75* .92= $3.45
2.1* 1.10= $2.31
$3.45
+ $2.31
_______
$5.76
The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.
x^3+5x^2-6x-30
(x^3+5x^2)+(-6x-30)
x^2(x+5)+(-6x-30)
x^2(x+5)-6(x+5)
(x^2-6)(x+5)
-------------
Answer: (x^2-6)(x+5)
