(i) x2 + xy (1 + y) + y3
(ii) y2 – xy (1 – x) – x3
Answer :
(i) x2 + xy (1 + y) + y3
Above question can be written as,
x2 + xy + xy2 + y3
Take out common in all terms,
x(x + y) + y2(x + y)
(x + y) (x + y2)
(ii) y2 – xy (1 – x) – x3
y2 – xy (1 – x) – x3
Above question can be written as,
y2 – xy + x2y – x3
Take out common in all terms,
y(y – x) + x2 (y – x)
(y – x) (y + x2)
