Question

find quadratic polynomial in X whose sum and product of zeroes are 5 and 21 upon 4

Answer 1

Hii friend,

Sum if zeros = (Alpha + Beta) = 5.

Product of zeros = (Alpha × Beta) = 21/4

Therefore,

QUADRATIC POLYNOMIAL = X²-(Alpha+beta)X + Alpha × Beta.

=> X²-5X + 21/4

=> 4X²-20X+21 = 0

Hence,

QUADRATIC POLYNOMIAL = 4X²-20X+21.
