What is the discriminant of 3x2 + 6x = 2?

Softa [21]

Answer:

Discriminant is 60

Step-by-step explanation:

the discriminant of $3x^2 + 6x = 2$

To find discriminant , first we write the equation in the form of

$ax^2+bx+c=0$

$3x^2 + 6x = 2$

Subtract 2 on both sides

$3x^2 + 6x-2=0$

a=3, b=6, c=-2

Formula for discriminant is $b^2-4ac$

Plug in the values

$b^2-4ac=(6)^2-4(3)(-2)=60$

Discriminant is 60
