y=x^2-3x+c and y=k-x-x^2 meet at
what are the values of c and k??
omg ive tried 100 ways but cant find the correct ans...please help??
"Way" number 101 is easier:
From the first equation and the fact that (-2,12) is a solution,
12 = 4 + 6 +c
So c = 2
Similarly, from the second equation, with (-2,12) being a solution of that also,
12 = k +2 -4
k = 14
