Question

Write the discriminant of quadratic equation ax2+bx+c=0

Answer 1

Hi!

In any quadratic in the form you have given (
`ax^2+bx+c=0`), the discriminant is ALWAYS

`b^2-4ac`

Given the quadratic formula:

`x=(-b+/-√(b^2-4ac) )/(2a)`

-------------------------------------------------------------------------------------------------------------

The discriminant would be the part of the equation that is under the square root.

-------------------------------------------------------------------------------------------------------------

Therefore, your answer is
`b^2-4ac`
