Question 1043804: solve by using your graphing calculator:
1. x^2-8x=-18
2.13x^2+24x-1=-14

x^2-8x+18=0
It has no real roots.
the discriminant (b^2-4ac)=(64-72)=-8
You input the function in Y= and push graph.

13x^2+24x+13=0, adding 14 to both sides.
This, too has no real roots. The discriminant is (576-676)=-100
