Question

Algebra 2 semester 2 help please? Rational Functions. http://prntscr.com/6mzt4u

Answer 1

16 is substitution, when n=1/2 does it make a true statement

rational can be thought of as 'looks like a fraction'

rational functions are just glorified fractions and all the rules of fractions apply to them

Answer 2

I don't understand how to do 17. :o

Answer 3

well, the simplest thing to do would be to clear the denominators; so multiply thru by 5-p

Answer 4

when does:

5-p^2 = -2(5-p)

Answer 5

might need to know the quadratic formula to solve for p if you aint to good at factoring

Answer 6

Answer 8

that looks really wrong

Answer 9

you dropped the negative on the 2 at the start ...

Answer 10

and you forgot to ... let me spot a few things for you

Answer 11

5 - p^2 = -2(5-p)

5 - p^2 = -10+2p

- p^2 =2p -15

0 = p^2 +2p -15

Answer 12

Whaaaat :o Oh man I should not have started this quiz

Answer 13

5 and -3 are factors of -15 that add up to 3, so we can facotr this into 2 pieces

0 = (p-3)(p+5)

now when does p-3=0? when does p+5=0?

Answer 14

p=3 and p=-5.

Answer 15

thats the solutions for p

as long as 5-p doesnt equal 0 we are good to go ... cant divide by a zero after all.

5--5=10 so we are good

Answer 16

thank you

Answer 17

so much :)

Answer 18

good luck with it
