### Enter the Quadratic Function using your Memory Keys

For example: 0 = 2x^{2 }+ 5x – 6

Make sure you are in Normal mode by pressing 0.

We know that a = 2; b = 5 and c = -6. We need to store this in the calculator. So we press 2 . Now store b so type 5 . And put c in so type 6 .

Now type in the formula by pressing 4 2

Your first answer will be which is -3.07… when you press .

Now to get your second answer you need to press until your cursor is behind the minus sign. Press . Your second answer will now be which will be 0.57… when you press on your SHARP EL535.

If you have another question e.g. 4×2 + 3x – 9 simply re-store the new a, b and c values, press up until you reach the previous quadratic formula and press then the new answer will appear.
