Question

factorise1 + x + xy + x^2y​

Answer 1

Step-by-step explanation:

x²Y+xy+x+1=0

xy(x+1)+1(x+1)=0

x=-1

xy=-1

y=1 OK friend this is urs answer

Answer 2

Answer:

Step-by-step explanation:

x^2-y^2-2y-1

=x^2-(y^2+2y+1)

=x^2-(y^2+2•y•1+1^2)

=x^2-(y+1)^2

=[x+(y+1)][x-(y+1)]

=[x+y+1][x-y-1]

Hope it helps
