Answer 1

For a quadratic equation
ax²+bx+c = 0 ...(1)
the discriminant is the algebraic value of
b²-4ac

For any given quadratic, you would rearrange it to have the form of equation (1) above, and calculate b²-4ac.

For example,
x^2 = 4
can be written as
x^2 + 0x -4 =0
where a=1, b=0, c=-4.

You can now proceed to calculate the discriminant.
