Question

Factorise :-

x3 + 13x2 + 32x + 20​

Answer 1

Answer:

(x+1)(x+2)(x+10)

Step-by-step explanation:

putting x= -1 we get 0

therefore x+1 is a factor of the given polynomial

now

dividing the polynomial by x+1 we get x^2+12x+20

the other factors will be obtained from the quadratic

factorise the quadratic we get

(x+2)(x+10)

Answer 2

Hope it helps you..

So at last..

the answer is (x+1) (x+2) (x+10)
