Answer 2

Answer:

-2,-10,-1

Step-by-step explanation

substitute -2 in the equation

-2 | 1           13                  32                 20                     only constants

     0           -2                 -22               -20

________________________________

=    1             11                  10                 0

first keep 0 and multiply with -2 and do multiply by sum

now you will get quadratic equation

x^2+11x+10

x^2+10x+x+10

taking x as common

x[x+10]1[x+10]

x=-10

or

x=-1

these are the factors of given polynomial

this will be helpul to you for any polynomial
