Question 211407: 10y^2-250/4y^2-100

You can put this solution on YOUR website!
The key step here is FACTORING! And the first step in ANY factoring problem is to take out the COMMON FACTOR!

10y%5E2+-+250%29%2F%284y%5E2+-100%29+

%2810%28y%5E2-25%29%29+%2F%284%28y%5E2+-25%29%29+

Normally, I would go another step to factor the y^2 -25, but this is not necessary here since the y^2 -25 divides out.

+10%2F4
5%2F2

If you have trouble with this type of problem, please see my own website by clicking on my tutor name "Rapaljer" anywhere in algebra.com. Look near the top of my homepage for "Basic, Intermediate, and College Algebra: One Step at a Time". Choose "Basic Algebra". If you need help with fractions, look in Chapter 3. If you need help with factoring, look in Chapter 2 for several topics on Factoring. A lot of these problems are also solved in my "MATH IN LIVING COLOR" pages. For more advanced problems, see Intermediate Algebra, Chapter 2 for both Factoring and Fractions. I hope this is helpful to you!
