Question

Factorise this! My answer is not correct plz help me!

Answer 1

1st start checking from lowest number where eqn becomes 0. like 0,1,-1,2,-2. most of the ques will get solved .if u get one root easily u can divide that with equation ,to get eqn of small degree. and then u can solve easily

Answer 2

let p(y)= 2y^+y^_2y_1

Explanation:

and g(y) = y+1 is the factor of p(y) So by the factor theoram y+1=0 y=1. p(_1) = 2*(_1^) +(_1)^_2*(_1)_1. =_2+1+2_2 =0
