Question

What is the discriminant D of the equation? 3g² + 15g + 10 = 0

Answer 1

D=b^2-4ac=225-4x3x10=225-120=105

Answer 2

Discriminant D of the equation 3g² + 15g + 10 = 0 is 105 .

Explanation:

Formula

`D = b^(2) - 4ac`

As the equation given in the question

3g² + 15g + 10 = 0

The general form of equation is in the form .

ax² + bx + c = 0

a = 3 , b = 15 , c = 10

Put all the values in the formula

`D = 15^(2) - 4* 3* 10`

As

15 ² = 225

`D = 225 -120`

D = 105

Therefore the discriminant D of the equation 3g² + 15g + 10 = 0 is 105 .
