Addition property
Step-by-step explanation:
The plus sign in the question tells us it’s an addition property
Answer:
(x-4) (x-3) (x+3)
Step-by-step explanation:
x^3 - 4x^2 - 9x + 36
Make 2 groups
x^3 - 4x^2 - 9x + 36
We can factor out x^2 from the first group and -9 from the second group
x^2 (x-4) - 9(x-4)
Now factor out (x-4)
(x-4) (x^2 -9)
This may be an answer choice but we can still factor
(x^2 -9) is the difference of squares
(x^2-9) = (x-3) (x+3)
Replacing this
(x-4) (x-3) (x+3)
Answer:11x²+8x²-9

Answer:
(-5,-7)
Step-by-step explanation:
Set functions equal to each other.
2x+3= -4x-27
2x+4x = -3-27
6x=-30
x= -5
f(-5) = 2(-5) +3
f(-5) =-10+3 y= - 7
g(-5) = -4(-5) -27
g(-5) =20-27 y= -7
x=-5 y=-7
(-5,-7)
