Question

Find the discriminant of 3x^2-10=-2

Answer 1

Answer:

its 76. i did the test and got 96 wrong.

Step-by-step explanation:

Answer 2

Answer: $D=96$

Step-by-step explanation:

You must add 2 to both sides of the equation:

$3x^2-10+2=-2+2\\3x^2-8=0$

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

$D=b^2-4ac$

Based on the given equation, you have that:

$a=3\\b=0\\c=-8$

Susbstitute values. Then you obtain:

$D=0^2-4(3)(-8)=96$
