how do you answer this algebraic expression (description)

Question

4x^2 + 2x^2 y   12 - 18x

  -------------         *  --------

  8x^2 - 12x^3       1

 

Answer 1

You need to factor the expression so that you can cancel out terms.

 

 

2x²(2 + 2y)               6(2 - 3x)

__________     *    ___________

 

4x²(2 - 3x)                     1

 

 

 

(2 - 3x) on the top and bottom cancel each other out.  x² also cancel each other out.  We end with

 

 

3(2 + 2y)
