Question 178214: After fully simpifying the expression
2*x^2+7*x+3 over x^2+3*x-4 divided by x^2+7*x+12 over 2*x^2-3*x+1
The numerator is (2*x+1)*(2*x-1)
The denominator is
Remember to invert and multiply, factor and cancel
Ok, I can get the numberator, but I am not sure how to get the denominator, any help with is problem will be greatly appreciated. Thank you.

First thing is to factor each of the polynomial expressions:









So the expression becomes:



Now invert and multiply:



Eliminate factors common to both numerator and denominator:



The numerator binomials are a conjugate pair, so the product is the difference of 2 squares, and the product of the denominator can be found by applying FOIL:
