Question

divide x3 +13x2+32x+20 by x+1 by long division method

Answer 1

hope this answer will be helpful ^_^

Answer 2

1 Step: put x=-1

(-1)³+13(-1)+32(-1)+20

-1-13-32+20=13-12=1-1=0

2 Step: above

3Step: factorise::

x²+12x+20

take the last and first polynomial i.e. x²×20=20x²

take factors of 20x² in rough

1×20

2×10

x²+10x+2x+20

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

(x+2) (x+10)

Ans is (x-1)(x+2)(x+10)
