Question

What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x? Discriminant = b2 – 4ac –8

Answer 1

Answer:

$16$

Step-by-step explanation:

The discriminant of a quadratic in standard form $ax^2+bx+c$ is given by $b^2-4ac$.

The quadratic $-3=-x^2+2x$ in standard form is $-x^2+2x+3$. Thus, we can assign the following values:

• $a$ of -1
• $b$ of 2
• $c$ of 3

Therefore, the discriminant of this quadratic is $2^2-4(-1)(3)=4+12=\boxed{16}$
