Step-by-step explanation:
p(x)=x cube+13x square+32x+20
p(-1)=(-1)cube+13(-1)square+32(-1)+20
p(-1)=-1+13-32+20
p(-1)=33-33
p(-1)=0
(x+1) is a factor of (x cube+13x square+32x+20)
Divide (x cube+13x square+32x+20) with (x+1)
Quotient=x square+12x+20
Factorise (x square+12x+20)
Factorisation:- x square+10x+2x+20
x(x+10)+2(x+10)
(x+2)(x+10)
•x cube+13x square+32x+20=(x+1)(x+2)(x+10)
