Answer: [tex]D=96[/tex]

Step-by-step explanation:

You must add 2 to both sides of the equation:

[tex]3x^2-10+2=-2+2\\3x^2-8=0[/tex]

You can find the discriminant of the quadratic equation given in the problem with the formula shown below:

[tex]D=b^2-4ac[/tex]

Based on the given equation, you have that:

[tex]a=3\\b=0\\c=-8[/tex]

Susbstitute values. Then you obtain:

[tex]D=0^2-4(3)(-8)=96[/tex]
