Answer:
The discriminant of 3 x squared minus 10 x = negative 2 is 76
Step-by-step explanation:
Given:
![3x^2-10x=-2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/smls29eukdls2yp51o2vmpabrp4njcro0h.png)
..........(1)
We can find out the discriminant by using the formula
![D=b^2-4ac](https://img.qammunity.org/2020/formulas/mathematics/middle-school/m6hc4jrsclve3ufwkeqspgpvwrc0ui7ewj.png)
So from the equation (1)
We have b = -10
a= 3
c= 2
Now put all these values of a,b and c in the formula of discriminant to find out the value of D
So
![D=(-10)^2-4(3)(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/o9oajd65989ju60vc3e99fmx17j9cuody7.png)
![D=100-24=76](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pz07qp86cjoha3xe5gpk6m4842zlu1c19n.png)
D=76
So the discriminant of the given quadritic equation = 76
