Question

x cube+13 x square+32 x+20​

Answer 1

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)
