Question

What is the value of the discriminant 3x^2 + 7x – 4

A. 1

B. 97

C. 56

D. 0​

Answer 1

B. 97

Explanation:

The discriminant of a quadratic equation in the form ax^2 + bx + c is given by the formula Δ = b^2 - 4ac.

For the equation 3x^2 + 7x - 4, the coefficients are:

a = 3

b = 7

c = -4

Plugging these values into the formula for the discriminant, we get:

Δ = (7)^2 - 4(3)(-4)

= 49 + 48

= 97

Therefore, the value of the discriminant for the quadratic equation 3x^2 + 7x - 4 is 97.

Answer 2

3x^2 + 7x - 4.

a = 3, b = 7, c = -4.

(7)^2 - 4(3)(-4)

= 49 + 48

= 97.

3x^2 + 7x - 4 is 97.

B. 97
