      6x^2                              x^2 - 3x

This exercise seems to be popular, lately.

Start by factoring everything. Cancel common factors in each ratio.

Then change it from dividing by the ratio to multiplying by the reciprocal of the ratio.

Please show us how far you get, if you want more help, or explain why you're stuck.
