Question

Factorise: x²y + xy + x + 1 using Factorisation by Regrouping terms wala method​

Answer 1

Answer:

(xy+1)(x+1)

Step-by-step explanation:

let us group the polynomial ibto 2 groups

=(x²y+xy)+(x+1)

common factor in the first group

is xy and in second is 1

so

=xy(x+1)+1(x+1)

=(xy+1)(x+1)
