Answer

Correct answer is D because sum of zeros is - b/a.
But product of zeros is c/a.

Answer

Sum of zeros..

Answer

Ellabarote sridharacharya formula ...from there we get sum of zeros of this equation =  -b/a

Answer

Option D is correct becausé in this polynomial there is no constant value so option a and b are incorrect and product of zeroes is c/a so, there is only one which is equal to -b/a and that is the sum of the zeroes of any polynomial.

Answer

Correct answer is option D since it shows the relationship between zeroes and its coefficients... Given that sum of zeroes= -b/a.

Answer

Because this is the formula which should be used.(alpha + beta = -b/a.)which is the sum of zeros. in which a=a, b= b. then by using formula we get -b/a.

Answer

Explanation:

The given quadratic equation is p(x) = ax^2 + bx + c.

The sum and product of the zeroes of the quadratic equation are given by:

Sum of zeroes = -b/a

Product of zeroes = c/a

So, we need to find the sum of zeroes which is -b/a.

Let the roots of the quadratic equation be α and β.

Then, we can write the quadratic equation as:

p(x) = a(x - α)(x - β)

Expanding the above expression, we get:

p(x) = ax^2 - a(α + β)x + aαβ

Comparing this with the given quadratic equation, we get:

-b/a = -(α + β) = sum of zeroes

c/a = αβ = product of zeroes

Therefore, the sum of zeroes of the quadratic equation p(x) = ax^2 + bx + c is -b/a, which is the answer option D.

Answer

Sum of zeroes =b/a

Answer

Answer

Answer is d because of the relation of zeroes and coefficient of a quadratic polynomial

Answer

Because it is the identity of ax2+bx+c  lambda and beta. =- b\a.

Answer

*Can you explain this answer*

Answer

Option d is the correct answer as alpha + beta = -(b)/a is an identity where b is the coefficient of x and a is the coefficient of x².
