How to factor x^3 - 4x^2 - 9x + 36 by grouping

const2013 [10]

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)

Can u please answer this question ASAP

REY [17]

Set both y’s equal to each other.

2x-1 = 3x+4
2x-3x = 4-(-1)
-x = 5
x = -5

Plug x = -5 into any of the given equation. I will use the first one as an example.

y = 2x-1
y = 2(-5)-1
y = -11

Answer: (-5, -11)
