 Question 362032: I need help on factoring polynomials math is my weakest subject and I need a lot of help on it. Here are some examples of problems I need help on: 1. 12m^5n^2+9m^4n+6m^3n^2 2. 6x^2+3x-15 3. 6x^4-10x^3+3x^2 and I would really appreciate if I can have the steps on how to solve these and problems like these because I'm not really understanding how the book is explaining it. Thank you. Click here to see answer by edjones(7794)

 Question 362058: I need to find the quotient and show all work This is what I have 64x^2 / 8x = 8x -100y^2 / 10y = -10y Is this correct? Can this be solved using long division. I tried that way but it doesn't come out right. I appreciate any help you can give me Thank you! Click here to see answer by solver91311(18785)
