Step-by-step explanation:

Let the zero es be a,b,y

Given zeroes are -3,2,1

Sum of its zeroes :-

a+b+y = -3+2+1

= -1+1

= 1

sum of the product taken two at a time :-

ab + by + ya = -3*2+2*1+1*-3

= -6+2+ -3

= -4 + -3

= -7

product of its zero :-

aby = -3*2*1

= -6

Therefore it's cubic polynomial is x³- (a+b+y)x² + (ab + by + ya) x - (aby)

-1x³ + -7x² + -6x

-1x + x + x + x + -7 x + x + x + -6 x

=0
