Question

hi Guys ...
Factorise with Factorisation method...
plz ....​

Answer 1

Answer:

y^2-xy(1-x)-x^2

= y^2-xy+x^2 y -x^2

=y^2-x^2 -xy+x^2

=(y+x)(y-x)-x(y-x)

=(y-x)(y+x-x)

=y(y-x)

Answer 2

${y}^{2} - xy(1 - x) - {x}^{2}$

$= {y}^{2} - xy + {x}^{2} y - {x}^{2}$

$= {y}^{2} - {x}^{2} - xy + {x}^{2}$

$= (y + x)(y - x) - x(y - x)$

$= (y - x)(y + x - x)$

$= y(y - x)$
