Final Answer is 2

Answer

• A quadratic equation is a polynomial with a polynomial of order 2 which means the highest power of is 2.
•The zero of a polynomial means that the value of x for which the polynomial becomes zero.
•For checking the number of zeroes of a quadratic equation we need to find the value of the discriminant which is D=16-8=8.
•As the value of D>=0 then it has unequal and real roots.
Hence, the given equation has two zeroes.

Answer

Solution:

Number of zeros of a quadratic equation is equal to the number of distinct roots of the equation.

The given quadratic equation is:

x^2 + 4x + 2a = 0

We can find the number of zeros of the quadratic equation by finding the number of distinct roots of the equation using the discriminant.

The discriminant of the quadratic equation is:

D = b^2 - 4ac

where a, b, and c are the coefficients of the quadratic equation.

Substituting the values of a, b, and c in the above formula, we get:

D = 4^2 - 4(1)(2a)

D = 16 - 8a

Now, we can determine the number of zeros of the quadratic equation based on the value of the discriminant as follows:

If D > 0, then the quadratic equation has two distinct real roots.

If D = 0, then the quadratic equation has one real root (which is repeated).

If D < 0,='' then='' the='' quadratic='' equation='' has='' no='' real='' roots='' (it='' has='' two='' complex='' conjugate='' />

In this case, we have:

D = 16 - 8a

For the quadratic equation to have two distinct real roots, we need D > 0.

Therefore, we have:

16 - 8a > 0

8a < />

a < />

So, for all values of a less than 2, the quadratic equation x^2 + 4x + 2a = 0 has two distinct real roots.

Therefore, the number of zeros of the quadratic equation is 2.

Hence, the correct option is (B) 2.

Answer

Correct option B

Answer

Correct answer is option B as the highest degree of this polynomial equation is 2

Answer

2, because the equation has two real roots.

Answer

The answer is 2 because the given equation has two Zeroes.

Answer

To find the number of zeros of the quadratic equation x² - 4x + 2, follow these steps:

The equation is in the form of ax² + bx + c, where:
- a = 1
- b = -4
- c = 2
Use the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a.
Calculate the discriminant (b² - 4ac):
- (-4)² - 4(1)(2) = 16 - 8 = 8
Since the discriminant is positive, there are two real zeros.

Therefore, Option B is the correct answer.

Answer

2 bcs. its degree is 2

Answer

As the degree of the equation is 2 there will be two zeros of the equation

Answer

Answer is 2

Answer

The answer is option b.2 because it is a quadratic equation

Answer

Because of degree of polynomial

Answer

For the quadratic polynomial ax2+bx+c, if D=b2−4ac≥0 , then the quadratic polynomial has two real zeros.

Here, the given quadratic polynomial equation is x2+4x+2=0

Therefore,

D=42−4×1×2

=16−8

=8≥0

Since,

D≥0

Therefore, the given equation has 2 real roots.

Answer

Option b is is correct as 2 has 0 degree of polynomial

Answer

2 zeros are the cause the highest degree is 2

Answer

Answer is option b) x^2 +4x+2

Since the degree of this polynomial is 2. So, the maximum number of zeroes is two.

Note: Don't always rely on this method for example:x^5 - x

=x[x^4 - 1]

=x[{x^2}^2 - 1^2]

=x[{x^2+1}{x^2-1}]

=x[{x^2+1}(x+1)(x-1)]

We can still reduce this into its roots.

Hence, if these kinds of questions I would request you to factorize then find the answer. If not possible to factorize you can see the degree of the polynomial then write the answer.

In competitive exams you can find the degree of polynomial then write the answer(for the question i gave better factorize then write the answer, no need to reduce into its root form.)

Answer

The number of zeroes of x²+4x+2 is 2.

A quadratic equation is a polynomial with a polynomial of order 2 which means the highest power of is 2.

The zero of a polynomial means that the value of x for which the polynomial becomes zero.

For checking the number of zeroes of a quadratic equation we need to find the value of the discriminant which is D=16- 8=8.

As the value of D>=0 then it has unequal and real roots.

Hence, the given equation has two zeroes.

Answer

Yes, the given equation have two zero
