Question

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

Answer 1

Answer:

The value of discriminant D for the given equation is 105.

Step-by-step explanation:

The given equation is

$3g^2+15g+10=0$                .... (1)

If a quadratic function is defined as

$ax^2+bx+c=0$                    .... (2)

then the discriminant D is

$D=b^2-4ac$

On comparing (1) and (2), we get

$a=3,b=15,c=10$

The value of discriminant D is

$D=15^2-4(3)(10)$

$D=225-120$

$D=105$

Therefore the value of discriminant D for the given equation is 105.

Answer 2

the discriminant D of the equation 3g² + 15g + 10 = 0
for a quadratic equation   ax²+bx+c=0
the discriminant D is D= b²-4xaxc
 so for  3g² + 15g + 10 = 0 D=15²- 4x3x10=125-120=5, so D=5
