Answer:
The answer to your question is x - 5 or x = 5
Step-by-step explanation:

1.- Factor the numerator
x² - 3x - 10
find 2 numbers that added equal -3 and multiply equal -10.
These numbers are -5 and + 2
(x - 5)(x + 2)
2.- Simplify

Delete (x +2) in both numerator and denominator
3.- Result x - 5
x = 5
The answer is R=18 I hope this helps

I'm not 100% sure
Answer:
(2x + 1) (x + 2)
Step-by-step explanation:
2x² + 4x + 1x + 2
They are already arranged, so you just have to find the GCF. 2x² + 4x have the GCF of 2 and 1x + 2 have the GCF of 1.
2x (x + 2) + 1(x + 2)
Now you divide the whole thing by x + 2.
2x (x + 2) + 1(x + 2)/ x + 2
One of them cancels out leaving (2x + 1) and (x+2)
