Question 118 • EA Academy Online Learning and Digital Citizenship Elective Spring

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2?

Answer

a = 5, b = 4, c = 2

a = 5, b = –4, c = –2

a = –4, b = 5, c = –2

a = 4, b = –5, c = –2

Explanation

Write the equation in the standard form ax² + bx + c = 0. Reordering 0 = 5x − 4x² − 2 gives −4x² + 5x − 2 = 0, so a = −4, b = 5, and c = −2. This matches choice C.
