SOLUTION: 23645=a(2)^2+b(2)+c 32015=a(20)^2+b(20)+c 33715=a(40)^2+b(40)+c When I tried to put this in quadratic form I got H=10t^2+245t+23115 From here I got stuck and couldn't figure

Question 379097: 23645=a(2)^2+b(2)+c
32015=a(20)^2+b(20)+c
33715=a(40)^2+b(40)+c
When I tried to put this in quadratic form I got
H=10t^2+245t+23115
From here I got stuck and couldn't figure out where to go. The assignment says to solve the quadratic formula.
