Question

Somebody pleaze help me, I am in a college algebra class and right now we r dealing with rational expressions. I need help in understanding how to add, subtract, mulitiply and divide them. If anybody knows some websites that can give me step by step explaination or if anybody can explain it to me I would really appreciate it.

Thanks.

THIS IS 4 JOHN G THE JACKASS. I AM N COLLEGE AND I STATED RATIONAL EXPRESSIONS NOT RELATIONAL EXPRESSIONS. WHAT THE HELL IS THAT ANYWAY? I WOULD APPRECIATE IT IF U WOULD GET UR FACTS STRAIGHT FIRST, BECUZ U HAVE NO IDEA AS TO HOW OLD I AM U F*CKING JERK!

Answer 2

vertical asymptote is the position y is undefined enable y = f(x)= -2x+2/x hence y = -2x^2 + 2 = 2( -x^2 -a million ) = 2 (a million+x) (a million-x) hence y is undefined at x = -a million and x = a million those are vertical asymptotes horizontal asymptotes is value of y even as x techniques infinity : y = -2x^2 + 2 even as x is going to infinity +2 and coffecient of x^2 will change into negligible hence y= -x^2 it truly is y techniques unfavourable infinity : )

Answer 3

There is no way that relational expressions would be in a college course. It's no where near advanced enough. I did it in 7th grade. Stop trying to make yourself look older.
