Question 10 • CMS 2026-2027 NC Math 2 CREDIT RECOVERY

What is the value of the discriminant for the quadratic equation negative 3 is equal to negative x squared plus 2 x ? Discriminant is equal to b squared minus 4 A c

Answer
A
16
B
8
C
negative 8
D
4

Explanation

Write the equation in standard form by moving all terms to one side: x² − 2x − 3 = 0. Thus, a = 1, b = −2, and c = −3. The discriminant is b² − 4ac = (−2)² − 4(1)(−3) = 4 + 12 = 16, so the correct choice is A, 16.
