Solving Quadratic Equations by Factoring
1. 3r^2 -16r-7=5
This is a quadratice, (the highest power is 2) so there could be 0,1 or 2 real answers.
First take it all to one side by subtracting 5 from both sides.
After you do that I will look at what you have. So unless someone else answers first, the next post is yours.
