Q:
Find the discriminant of 3x2 - 10X=-2.
Accepted Solution
A:
Answer:76Step-by-step explanation:Given a quadratic in standard form : ax² + bx + c : a ≠ 0, thenthe discriminant Δ = b² - 4acGiven3x² - 10x = - 2 ( add 2 to both sides )3x² - 10x + 2 = 0 ← in standard formwith a = 3, b = - 10 and c = 2b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
