F(x) = x2 – 3x + 18
What is the discriminant of f

-63

Step-by-step explanation:

To find the discriminant, you just need to apply the square root part of the quadratic formula:

Sqrt (b^2 - 4ac)

Sqrt (9 - 4 x 1 x 18)

Sqrt (-63)

The number inside of the square root would be the discriminant.

A negative discriminant means that the quadratic would result in imaginary solutions.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
