Step-by-step explanation:
Hello Mate!
If zeros of p(x) polynomial are -2, -3 and -1.
This means that factors are x+2, x+3 and x+1.
So for that we will multiple all the factors for getting the polynomial.
p(x) = ( x + 1 )( x + 2 )( x + 3 )
p(x) = ( x² + 2x + x + 2 )( x + 3 )
p(x) = ( x² + 3x + 2 )( x + 3 )
p(x) = x³ + 3x² + 2x + 3x² + 9x + 6
p(x) = x³ + 6x² + 11x + 6.
Have great future ahead!
