Question 117924: Hello, can you please help me understand step by step how to divide this kind of problem: Divide:
2x^2+5x-12 over 9x^2 divided by 2x^2-7x+6 over 3x^2-x-4
To my understanding, we are to rewrite the problem as multiplication, and then factor out the polynomials. When I did this, my answer was incorrect and I am not sure what the correct steps to take are. Any help is greatly appreciated.
Thank you

Question 117925: Can you please explain how this problem is solved in detailed steps?
My directions say to perform the indicated operations:
√[50] + 2√[32] – √[8]
I am confused, because I thought the square root of an answer was two numbers that multiply together to get that number?
I am completely lost with this, detailed step by step directions would be greatly appreciated.
Thank you
Patti

Question 118200: I'm trying to solve the following equation:
The square root of [x+10] plus the square root of [x-6] equals 8.
I tried squaring both sides, and that eliminates some radicals, but it also creates some more!

2. The denominator of a certain fraction is three times the numerator. If one is added to the
numerator and subtracted from the denominator, the result equals 1/2. Find the original fraction.
3. The denominator of a fraction is 5 more than the numerator. If 5 is added to the numerator and 2 is added to the denominator, the value of the fraction is 8/9. Find the original fraction.
4. The numerator is one less than the denominator. If two is added to the denominator and
subtracted from the nomerator, the value of the fraction is 1/2. Find the original fraction.

Question 119853: I need some help with this problem I can figure it out without the negative sign but I am not sure what to do with the negative sign.
I have to evaluate if possible. The question is -sqrt81.
So I am thinking that -sqrt81 is a perfect square so the answer would be -0. If I am not right could you please help me figure it out.
