Question

METAL and FAN( if explained enough and is the correct answer) simplify the expression. state any excluded values 2r^2+9r-5/r^2+10r+25

Answer 1

well you need to factor the numerator and denominator

excluded values occur in the denominator

so the factored form is

\[\frac{(2r -1)(r + 5)}{(r + 5)^2}\]

hopefully that helps

Answer 2

i dont know what to do after that though

Answer 3

Answer 4

I was not the best at this topic, but if I remember correctly
if it cancels, there is a Hole at that "zero"
and if it stays in the denominator, there is an asymptotic there because you can't divide by 0

for example
(x+3)(x-3) (x-3)
--------- = ------
(x+3)^3 (x+3)
one of the (x+3) had been canceled, so there will be a Hole at x = -3
then there is still a (x+3) in the denominator, so there will be an asymptote at x = -3

Answer 5

thank you i think r is 1

Answer 6

could you factor some more questions for me

Answer 7

\[5t^2+6-8/3t^2+5t-2\]
