Question

What is the discriminant of 3x^2-10 x = -2

Answer 1

76

Explanation:

Given a quadratic equation in standard form (ax² + bx + c = 0 , a ≠ 0 ), then

the discriminant is

Δ = b² - 4ac

Given

3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10, c = 2 , then

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76

Answer 2

76

Explanation:

Calculation of the discriminant of the polynomial : 2−10⋅x+3⋅x2

The discriminant of the polynomial 2−10⋅x+3⋅x2 is equal to 76
