You can put this solution on YOUR website!
yes...exactly
Now you can find cubes....27r^6= 3r*3r*3r.... and -3p^6 =- -1p^2* -1p^2* -1p^2 so you can make 3 binomials...... 3(3r^2-1p)(3r^2-1p^2)(3r^2-3p^2)Distribute to check and be sure that is the correct form...when you are done checking you should end up with what you started off with!
