Answer 2

SOLUTION

TO DETERMINE

The quadratic polynomial whose zeroes are are 3 & 5

CONCEPT TO BE IMPLEMENTED

If the Sum of zeroes and Product of the zeroes of a quadratic polynomial is given then the quadratic polynomial is

$\sf{ {x}^{2} -(Sum \: of \: the \: zeroes )x + Product \: of \: the \: zeroes }$

EVALUATION

Here it is given that the zeroes of the quadratic polynomial are 3 & 5

Hence the required Quadratic polynomial is

$\sf{ {x}^{2} -(Sum \: of \: the \: zeroes )x + Product \: of \: the \: zeroes }$

$\sf{ = {x}^{2} - (3 + 5)x + (3 \times 5) }$

$\sf{ = {x}^{2} - 8x + 15 }$
