What is the value of the discriminant for the quadratic equation −3=−x2+2⁢x? Discriminant is equal to b squared minus 4 A c

Write the equation in standard form: −3 = −x² + 2x becomes 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 answer is 16.
