so, first u r supposed to find a factor by factor theorem (the factor is x-2 or x=-20
then, u r supposed to do algebraic division and find the quotient. (the remainder should be 0)
After that, you use midterm breakup method on the quotient to find the two other factors.

I have mentioned detailed steps on how to solve this question, plz hurry up and tell me the answer, I also want working especially of steep two.
plz help, quick. ​
