Question

find the cubic polynomial , whose zeroes are -2,-3 and -1

Answer 1

hii. ......friend

the answer is here,

Sum of the zeroes ,

=> -2+(-3)+(-1)

=> -6.

Product of zeroes taken two at a time,

=> (-2)(-3) +(-3)(-1)+(-1)(-2)

=> 6+3+2

=> 11.

Product of zeroes,

=> (-2)(-3)(-1)

=> -6.


The cubic polynomial,

$= > \: {x}^{3} - (sum \: of \: zeroes) {x}^{2} + (product \: of \: zeroes \: taken \: two \: at \: a \: time)x - product \: of \: zeroes$

$= > \: {x}^{3} - ( - 6) {x}^{2} + 11x - 6$

$= > \: {x}^{3} + 6 {x}^{2} + 11x - 6$

:-)Hope it helps u.
