Answer 1

☞Question.

➝Find the quadratic polynomial sum of whose whose zeroes is 2 and product is -8.

☞Solution.

$\alpha \beta = - 8$

$\alpha + \beta = 2$

quadratic equation's formula is

➝$\sf\green{ x^2 +( a +B )x - a.B= 0}$

➝$\sf\green{ x^2 + 2x - ( -8 )= 0}$

➝$\sf\green{ x^2 + 2x + 8 = 0}$

so, quadratic equation is

➝$\sf\green{ x^2 + 2x + 8 = 0}$
