Question

3x^2+15x+25=−3x−2
whats the discrimate?​

Answer 1

- 315

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

Answer 2

The discriminate is 0
