Question

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

Answer 1

12 times something cannot equal to 2 unless it is a negative number,is there a negative number included?

Answer 2

Answer:

The discriminant of the given equation is 60

Step-by-step explanation:

$\text{Given the equation }3x^2+6x=2$

we have to find the discriminant of above equation.

$Equation:\thinspace 3x^2+6x-2=0$

$\text{Comparing above equation with general quadratic equation }ax^2+bx+c=0$

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

The discriminant can be calculated by the formula

$D=b^2-4ac$

$D=6^2-4(3)(-2)$

$D=36+24=60$

Hence, the discriminant of the given equation is 60
