Question

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

Answer 1

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

Explanation:

Answer 2

Answer:
`D=96`

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`
