Simplify each expression and state any excluded values help?!

Answer 1

3x^2+19x-14
over
x^2-49

Answer 2

Factor both out, and see if two factors cancel.

Answer 3

how do i do the top?

Answer 4

(3x +/- y)(x +/- z)

I gave you two, find y and z

Answer 5

thanks!

Answer 6

What answer did you get?

Answer 7

i got -7 for the z but i cant seem to get y for (3x+y ) so it looks like this mostly

(3x+y)( x+-7)

Answer 8

try y = -2 :)

Answer 9

Factored, it is (3x-2)(x+7), now just get rid of the factors of the denominator which cancel.

Answer 10

What do you get in the end?

Answer 11

ohh so its (3x-2)(x+7) or do u have to cancel the x+7 also?

Answer 12

\[\frac{ (3x-2)(x+7 }{ (x-7)(x+7) }\]

(x+7) / (x+7) = 1, so they cancel. In the end, you have:

(3x-2) / (x-7)

Answer 13

ok thanks! i got it now
