Question

What is the value of the discrimination for the quadratic equation -3=-x^2+2x

Answer 1

this is for the discriminant is thats what you mean by discrimination

Answer 2

-3 = -x^2 + 2

Solution:

Multiplying by -1 throughout;

3 = x^2 - 2x

x^2 - 2x - 3 = 0

Using the quadratic formula;

x = (b^2 +/-
`√(b^2 -4ac)`) × 1/2a

x = (2 +/- 4) × 1/2

x = 3 or -1
