Divide: r+5/r2+5r-14 by r2+4r-21/r-2

To solve this, multiply the first fraction by the reciprocal of the second fraction. For this question, multiply r+5/r^2+5r-14 by r-2/r^5+4r-21. You should get (r^2+3r-10)/(r^4+9r^3-15r^2-161r+294). Then, just use your exponent rules to get a final answer.

Bwould be the answer
