B.x2-2x+15

C.x2+2x+15

D.x2+2x-15​

Answer 1

Step-by-step explanation:

so the answer is option B thank you

Answer 2

Answer:

X^2 - 2x + 15

Step-by-step explanation:

Let alpha and bita be the zeros of the Quadratic polynomial

Given, alpha +bita = 2

alpha ×bita =15

We know that sum of zeros of a Quadratic polynomial = -b/a

And product of the zeros of a Quadratic polynomial = c/a

Where a = coefficient of x^2

b = coefficient of x

c = constant

Then - b/a = 2

- b = 2 , a = 1

b = - 2

And c/a = 15

c = 15

Therefore, required polynomial = x^2 - 2x + 15
