Question

If the sum of zeros is -1 and their product is seven then find the quadratic polynomial

Answer 1

Answer:

Let both the zeroes be x and y

By the question

x + y = -1                                ----------------(i)

x × y = 7                                ----------------(ii)

In equation (i)

x + y = -1

x = -y - 1

Substituting x in equation (ii)

( - y - 1)(y) = 7

-y² - y = 7

y² + y + 7 = 0

Hence the quadratic polynomial is y² + y + 7 = 0

Answer 2

Answer:

x square +x +7

Step-by-step explanation:

alpha + bita= -1

alpha. beta= 7

then,

k(x square - (alpha+ bita) + (alpha x bita)

therefore, K( Xsquare + X +7)
