x^2 + 2x - 15over 4x^2 divided by x^2 -25 over 2x-10 Will someone show me the steps to work this problem, I have looked and looked at my book but it still makes no sense to me. Help.
First, change the division to the reciprocal of muliplication. Check this, it depends on my understanding of your problem.
(x^2+2x-15) * (2x-10)/(x^2-25)
Now each of those can be factored, do so. It should reduce very quickly.
multiply by the reciprocal of the second fraction (...basically just flip it over)
originally you have....
x^2 + 2x - 15
x^2 - 25
2x - 10
Then you'll get
x^2 + 2x - 15 2x - 10
_____________ x _________
4x^2 x^2 - 25
Factor everything and simplify
You should then get your answer
Hope this helps!!!
sorry i don't know why it came out so messed up.
Try to follow the instructions of either bob or I (they are the same)
