Question

What is the discrimination 3x2-10x=-2

Answer 1

`6 - 10x = 2 \\ - 10x = 2 - 6 \\ 10x = 4 \\ x = 4 / 10`
thus x will be 2/5

Answer 2

D = 76.

Explanation:

Given : 3x² - 10x = -2.

To find : What is the discrimination.

Solution : We have given 3x² - 10x = -2.

By the formula : ax² + bx + c = 0.

Discrimination (D) = b² - 4ac.

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

D = (-10)² - 4(3) (2).

D = 100 - 24.

D = 76.

Therefore, D = 76.
