Question

2x^2 + 3x + 20 over x^2 - 5x - 36
my answer: 2(13x+5) over 5x -9

Answer 1

pleassseeeee answer:(((((

Answer 2

i need to study.

Answer 3

Hold on

Answer 4

ok:)

Answer 5

Did you divide the top one with the bottom one?

Answer 6

You will get something like this after synthetic division,
\[\Large 2+\frac{13x+92}{x^2-5x-36}\]
Then factor it,
\[\Large \frac{13 x+92}{(x-9) (x+4)}\]

Answer 7

We'll leave the "2" behind first, because we have to deal with partial fraction for that fraction.
After partial fraction you should get this
\[\frac{209}{13 (x-9)}-\frac{40}{13 (x+4)}\]
Add back the "2",
\[2+\frac{209}{13 (x-9)}-\frac{40}{13 (x+4)}\]

Answer 8

Actually your answer doesn't equal to your question, you can check that by substituting lets say x=5 into it,
For your question, if x=5, then y=-85/36
But for your answer, if x=5, then y=35/4
The 2 y's doesn't equal means your answer is wrong, this is just a method to check.

Answer 9

thats not an option dear:(
