Answer:

Final factor is (x-9)(x+4)

Step-by-step explanation:

Given expression is x^2- 5x- 36.

Now we need to factor that expression

x^2- 5x- 36

Find two numbers whose product is -36 and sum is -5.

Two such numbers oare -9 and +4. So we get:

=x^2- 9x+4x- 36

=x(x-9)+4(x-9)

=(x-9)(x+4)

Hence final factor is (x-9)(x+4)

cupoosta [38]

Answer:

x=11/5, or x=2.2.

Step-by-step explanation:

9-3(x+4)=2(x-3)-8

9-3x-12=2x-6-8

9-12-3x=2x-14

-3-3x=2x-14

-3-3x-2x=-14

-3-5x=-14

5x=-3-(-14)

5x=-3+14

5x=11

x=11/5

x=2.2
