Answer:
- 315
Step-by-step explanation:
Given a quadratic equation in standard form ax² + bx + c : a ≠ 0
Then the discriminant is
Δ = b² - 4ac
Given
3x² + 15x + 25 = - 3x - 2 ( subtract - 3x - 2 to both sides )
3x² + 18x + 27 = 0 ← in standard form
with a = 3, b = 18 and c = 27, then
b² - 4ac = 3² - (4 × 3 × 27) = 9 - 324 = - 315
