Division and Multiplication
In order to solve a division problem like (x2-2x+4)/(x-7) divided by 1/(x-2)(x+2), what is your fist step?
to flip the numerator an the denominator on the second fraction (in this case, it would be (x2-2x+4)/(x-7) divided by (x-2)(x+2)/1)
What do you do to the exponents in a simplification problem?
You subtract the exponents and put the final product on the side that had the bigger exponent.
(m-3/6m3) - (m+3/6m3)
-1/m3
Add (5/a2+3a+2) + (5a+1/a2+3a+2)

When graphing (x-2/x2+87) - (5x/ 3x+7) does it go through the origin.
Yes it goes through the origin
What is the difference between multiplying and dividing equations?
When you divide you have to switch the second fraction's denominator and numerator, then you can multiply. However, when you multiply that is all you do.
