Question

(x^3-49x)/(17x+119)
Simplify

Answer 1

are you able to factor x^3 - 49x ?

Answer 2

I don't know how to factor with only 2 things

Answer 3

well notice we have the GCF of x

Answer 4

so we can factor that out x*(x^2 - 49)

Answer 5

x(x^2+49)

Answer 6

minus, not plus

Answer 7

- not +

Answer 8

yeah

Answer 9

then factor x^2 - 49

Answer 10

that is a difference of squares

Answer 11

x-7

Answer 12

so x^2(x-7)?

Answer 13

close, you forgot about the (x+7) as well

Answer 14

x^2 - 49 factors to (x-7)(x+7)

Answer 15

okay so I have log(x(x+7)(x-7)/(17x+119)) but im still confused on what needs to be simplified still

Answer 16

where are you getting "log" ?

Answer 17

oh i forgot to add it in the original equation

Answer 18

gotcha

Answer 19

anyways, we factor the denominator 17x+119

Answer 20

we can factor out 17 to get 17(x+7)

Answer 21

I'm sure you see what cancels

Answer 22

yes thank you so much!

Answer 23

you're welcome
