quadratic eqn on casio fx991ms
hey im trying to figure out how to use the quadratic eqn on the calculator..
I go to mode, click until i get to eqn, press eqn
Press 2 for unknowns
Enter the a b c variables
(ax^2 +bx+c =0)
then it asks me for a2, b2, c2 (i dont know what that means)
and i just press 0 which then gives me math error
What am I doing wrong?
