How do I enter a quadratic equation in this calculator. I have tried what I wrote down in class. Sometimes it works, but most of the time it doesn't.
Thank you.
I like to take the a, b, and c values and store them as variables -
a->x
b->y
c->z
then run:
(- y + SQRT ( y^2-(4xz) ) )/2x
AND
(- y - SQRT ( y^2-(4xz) ) )/2x
the parentheses may be a bit confusing - 1 holds the whole top of the formula to be divided together, one holds everything under the square root, one holds the -4ac (or -4xz).
That ought to cover it.

CORRECTION: Testing reveals a problem. correct process below:

then run:
(- y + SQRT ( y^2-(4xz) ) )/(2x)
AND
(- y - SQRT ( y^2-(4xz) ) )/(2x)
the parentheses may be a bit confusing - 1 holds the whole top of the formula to be divided together, one holds everything under the square root, one holds the -4ac (or -4xz).
A parentheseis also encloses the bottom of the formula (2a or 2x)

X*x+bx+c=0
