Question

Simplify completely quantity x squared plus 4 x minus 45 all over x squared plus 10 x plus 9 and find the restrictions on the variable.

quantity x minus 5 over quantity x plus 1, x ≠ −1, x ≠ −9

quantity x minus 5 over quantity x plus 1, x ≠ −1, x ≠ 5

quantity x plus 5 over quantity x plus 1, x ≠ −1, x ≠ −9

quantity x plus 5 over x plus 1, x ≠ −1, x ≠ 5

Answer 1

Answer 2

@hartnn

Answer 3

\[x ^{2} + 4x - 45\] over \[x ^{2} + 10x + 9\] Is this the equation?

Answer 4

Yes @DocLav

Answer 5

Can you help me out?

Answer 6

I can try.

Answer 7

To simplify we need to factor the top and bottom.

Answer 8

Im really bad at this stuff lol

Answer 9

On the top the equation factors to \[(x + 9)(x - 5)\]

Answer 10

I know its x-5 over x-1 but not sure on the last part of the equation

Answer 11

The bottom factors to \[(x + 9)(x + 1)\]

Answer 12

So you are able to cancel out the \[(x + 9)\] from the top and bottom.

Answer 13

I think so

Answer 14

Ultimately you are left with x- 5 over x + 1. This is your final answer

Answer 15

Then what would be the end of the answer? since there is two x-5 over x+1

Answer 16

Does that help?

Answer 17

IM trying to figure out this part at the end of the equations of the answers x ≠ −1, x ≠ −9

Answer 18

So restrictions are where you can't have the top or bottom equal to 0.

Answer 19

So then the answer would be B?

Answer 20

So it would be the last one.

Answer 21

Sorry , yeah B.

Answer 22

Answer is D?

Answer 23
