Question

Factorise the expression
1+X+xy+x2y​

Answer 1

Answer:

18p2q2 – 24 pq2 + 30p2q

= 6pq (3pq -4q + 5p)

27a3b3 – 18a2b3 + 75a3b2

= 3a2b2 (9ab – 6b + 25a)

Answer 2

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Factorise the polynomial.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

$1 + x + xy + {x}^{2} y$

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

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

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $(1 + xy)(1 + x)$
