You can put this solution on YOUR website!
y=2x%5E2-5x%2B3
-
y=2%28x%5E2-5x%2F2%29%2B3
y=2%28x%5E2-5x%2F2%2B%285%2F4%29%5E2%29-2%285%2F4%29%5E2%2B3
y=2%28x-5%2F4%29%5E2%2B3-2%2825%2F16%29
2%28x-5%2F4%29%5E2%2B3-25%2F8
2%28x-5%2F4%29%5E2%2B24%2F8-25%2F8
2%28x-5%2F4%29%5E2-1%2F8


y=2%28x-5%2F4%29%5E2-1%2F8
Compare this to
y=p%28x%2Bq%29%5E2%2Br.


Looking at the corresponding parts,
system%28p=2%2Cq=-5%2F4%2C+r=-1%2F8%29
and you are asked to find q%2Br.
