Answer:
- 56
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac
Given
3 - 4x = - 6x² ( add 6x² to both sides )
6x² - 4x + 3 = 0 ← in standard form
with a = 6, b = - 4 and c = 3, thus
b² - 4ac
= (- 4)² - (4 × 6 × 3) = 16 - 72 = - 56
