Answer 1

Answer:

hame nahi ata very sorry

Answer 2

SOLUTION

TO DETERMINE

The quadratic polynomial whose zeroes are - 4 & - 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

We have to find the quadratic polynomial whose zeroes are - 4 & - 5

The zeroes are - 4 & - 5

Sum of the zeroes = - 4 - 5 = - 9

Product of the zeroes = ( - 4) × ( - 5) = 20

Hence the required Quadratic polynomial

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

$\sf = {x}^{2} - ( - 9)x + 20$

$\sf = {x}^{2} + 9x + 20$
