Question

What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x?

Discriminant = b2 – 4ac

Answer 1

hello :
–3 = –x²+ 2x
-x²+2x+3 = 0
a=-1 and b = 2 c= 3
b²-4ac = 2²-4(-1)(3) = 16

Answer 2

16.

Explanation:

In this equation we havve that a=-1, b=2 and c= 3.

Discriminant = 4-4(-1)(3) = 4+12 = 16.
