**Jayson**, Tuesday, October 30, 2012 at 10:54amThis is what I have so far if someone could help me finish.

a(-2)^2+b(-2)+c=1

a(0)^2+b(0)+c=5

a(4)^2+b(4)+c=-59

4a-2b+c=1

0a+0b+c=5 c=5

16a+4b+c=-59

4a-2b+5=1

16a+4b+5=-59

4a-2b+5-5=1-5

4a-2b=-4

16a+4b+5-5=-59-5

16a+4b=-64

Now I'm not sure if I'm doing this right.

4(4a-2b)=-4*4

16a+4b=-16

16a-8b=-16

16a+4b=-64

16a-8b-(16a+4b)=-36-(-64)

I'm lost!

Can someone please help?
