Question

2/y +4/y^2 - 1/y

Answer 1

what do you need help with?

Answer 2

I don't get how to solve this equation, do I multiply by y^2 to get the same denominator?

Answer 3

so do you need to find the value of y?

Answer 4

Its adding and subtracting rational expressions, it says to simplify and state any restrictions

Answer 5

well I would first subtract 2/y and 1/y which is 1/y. that would leave you with \[4/y^2 + 1/y\]

Answer 6

So y^2/y = y so the first fraction becomes 2y/y^2 then you do the same thing for the second fraction, y^2/y^2 = 1 so it becomes 4/y2 then for the last fraction you do the same thing y^2/y = y so y/y^2

Answer 7

thank you!!!

Answer 8

Final answer will be:

2y/y^2+ 4/y^2 - y/y^2 and then just add them

( 2y-y+ 4) / y^2 = (y+4)/y^2

glad to help!
