Ax^2 + bx + c = 0, the discriminant is b^2 - 4ac when I try to solve with option 26^2 - 4(2)(3) = 12So the price is 2

2.) 0 = 2x2 + 6x + 3

Step-by-step explanation:

The discriminant that a quadratic equation is the worth of

b^2 - 4ac

where the quadratic equation is defined as ax^2 + bx + c = 0

And

a = co-efficient that x^2

b = co-efficient that x

c = continuous of the quadratic equation

Considering the above and every the choices given, for

1.) 0 = –x2 + 8x + 2

a = -1, b = 8, c = 2

Discriminant = 8^2 - 4(-1)(2)

= 64 + 8 =72

Discriminant ≠ 12

2.) 0 = 2x2 + 6x + 3

a = 2, b = 6, c = 3

Discriminant = 6^2 - 4(2)(3)

= 36 - 24 =12

Discriminant = 12

3.) 0 = –x2 + 4x + 1

a = -1, b = 4, c = 1

Discriminant = 4^2 - 4(-1)(1)

= 16 + 4 = 20

Discriminant ≠ 12

4.) 0 = 4x2 + 2x + 1

a = 4, b = 2, c = 1

Discriminant = 2^2 - 4(4)(1)

= 4 - 16 = -12

Discriminant ≠ 12

Hence just equation 2.) 0 = 2x2 + 6x + 3 can be the equation.

You are watching: A quadratic equation has a discriminant of 12. which could be the equation?

alternative b i m sorry is

Step-by-step explanation:

We have been given the discriminant 12

We have actually to pick the equation i m sorry will meet the offered discriminant.

us will take into consideration all the provided equation one by one

First we will certainly take alternative a i m sorry is Discriminant native the equation we will find by the formula Here, a=-1,b=8 and also c=2 top top substituting the worths we will get Hence, option a is incorrect.

Now, us will take into consideration option b i m sorry is

Here, a=2,b=6 and also c=3 ~ above substituting the values we get Hence, alternative b is correct

Therefore, option b is the forced answer.

the prize is 2 :)

Step-by-step explanation:

0 = 2x2 + 6x + 3.

Step-by-step explanation:

For the equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.

b^2 - 4ac = 12

b^2 = 12 + 4ac

Consider the 2nd equation 0 = 2x2 + 6x + 3:

6^2 = 36 = 12 + 4*2*3 = 12 + 24 = 36

- for this reason that"s the one.

2x2+6x+

Step-by-step explanation:

44

step-by-step explanation:

the

Step-by-step explanation:

To discover discriminant we use formula  a= -1 , b= 8 and also c= 2 Discriminant is 72 a= 2 , b= 6 and c= 3 Discriminant is 12

So, has actually discriminant 12 Step-by-step explanation:

Since, the discriminant the a quadratic equation is, In very first option ,  In second option,  In third option,  In fourth option,  b or alternative 2
