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?

nvm i figured it out, turns out i didnt press out the arrow button to degree instead of unknowwns.

That function is great for solving equations, or even if you have a 2x2 or 3x3 matrix. Saves a lot of time.
