Question

Find a quadratic polynomial whose zeros are 1 and -3

Answer 1

Answer:

Let a= 1

and

b=-3

Sum of zeros =1-3=-2

Products of zeros =1×-3=-3

Hence, the quadratic polynomial is →kx^2+(sum of zeros)x+product of zeros

Putting the values in quadratic polynomial

kx^2+(-2)x+(-3)

Hence, the quadratic polynomial is →kx^2-2x-3

where k is constant.
