Question

Find the quadratic polynomial the sum and product of whose are 2/5 and 21 respectively

Answer 1

x^2-2/5x+21 will be the required polynomial

Answer 2

HI !

Sum of zeros = 2/5
Product of zeros = 21

A quadratic polynomial is given by :-
x² - (Sum of zeros)x + (Product of zeros)

x² - 2/5 x + 21                 ----> required polynomial
