Question

help me out in this question ..

Answer 1

In this question apply factor theorem at first, take out the factors of 20 and then put these factors one by one on the place of x whichever factor will give answer 0 is the zero of the polynomial then divide the whole equation by x+1 because -1 is the factor of 20 when you divide the equation with x+1 the quotient will be x square + 12x +20. Now multiply the x+1 by the quotient. The answer will be (x+1)(x+10)(x+2)

Answer 2

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