Question

What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x? Discriminant = b2 – 4ac –8 4 8 16

Answer 1

Equation:

-3 = -x² + 2x

Re-arranging the equation into the form ax² + bx + c:

-3 = -x² + 2x

Subtract (x² + 2) from both sides:

x² - 2x - 3 = 0

Find the value of the discriminant:

discriminant = b² - 4ac

a = 1, b = -2 and c = -3:

discriminant = (-2)² - 4(1)(-3)

discriminant = 4 + 12

discriminant = 16

Answer: The discriminant is 16
