Answer: x = 1/6 or 1.6667

Steps

3x * 2 + 6x = 2

Multiply the numbers: 3 * 2 = 6

6x + 6x = 2

Add similar elements: 6x + 6x = 12x

12x = 2

Divide both sides by 12

12x / 12  =  2 / 12

Simplify

x = 1/6

Answer:  The required discriminant of the given quadratic equation is 60.

Step-by-step explanation:  We are given to find the discriminant of the following quadratic equation :

[tex]3x^2+6x=2\\\\\Rightarrow 3x^2+6x-2=0~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

the discriminant of a quadratic equation [tex]ax^2+bx+c=0,~a\neq 0[/tex] is given by

[tex]D=b^2-4ac.[/tex]

For the given equation (i), we have

a = 3,  b = 6  and  c = -2.

Therefore, the discriminant of the given equation will be

[tex]D=b^2-4ac=6^2-4\times3\times(-2)=36+24=60.[/tex]

Thus, the required discriminant of the given quadratic equation is 60.
