Answer 2

The discriminant of $3x^2-10x=-2$ is 76.

Step-by-step explanation:

Given : $3x^2-10x=-2$

To find : The discriminant ?

Solution :

The general quadratic equation is $ax^2+bx+c=0$

The discriminant is $D=b^2-4ac$

On comparing with given quadratic equation $3x^2-10x+2=0$

Here, a=3, b=-10 and c=2.

Substitute the values,

$D=(-10)^2-4(3)(2)$

$D=100-24$

$D=76$

Therefore, the discriminant of $3x^2-10x=-2$ is 76.
