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

**drwls**, Wednesday, August 5, 2009 at 1:14amDo 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.

**MathMate**, Wednesday, August 5, 2009 at 8:23amPlease 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)/6= 1- (X+5)/7

I know you have to get a CD of 42 but I can't get the write answer.
