I'm subracting fractions that have denominators like x-3 and such. And the numerator for the answer is -x+3. So I was wondering if I could just simplify that and cross them both out...

I need to find the LCD from the denominators 9 and 7 but I don't know how to find it

i cant figure out the least common denominator for the numbers 9, 11, and 4

How do I find the (LCM) or the (LCD) of fraction? Is the LCM the same as the LCD? Do they have a link with each other?

How do I find the LCD of k2+k-42/1-k and k2-k-30/k-1
