2/y^2-3y+2 + 7/y^2-1

• algebra -

Do you mean
2/(y^2-3y+2) + 7/(y^2-1) ?
1/(y-1) can be factored out of both terms. That leaves you with
[1/(y-1)][2/(y-2) + 7/(y+1)]
That is not much simpler, however.
You could create a common denominator with the second bracketed term, but that won't simplify it much, either.

Please take care when transcribing questions involving fractions. All numerators and denominators have implicit parentheses around them, so when put onto a single line, they are necessary. An omission will change the value of the expression.

For example:
1/4x+3 is not the same as 1/(4x+3) because without parentheses division is done before addition.

(x+5)over 6= 1- (x+5) over 7

(x+5)/6= 1- (X+5)/7
I know you have to get a CD of 42 but I can't get the write answer.
