Question 1. Factorize $-3x ^{2}y-3x+9xy ^{2}$

— algebra

Solution:

$-3x ^{2}y-3x+9xy ^{2}$

To factorize this expression we can see that 3x is common term among all three terms of the expression – which we take out and put brackets around the remaining factor.

$-3x ^{2}y-3x+9xy ^{2}$

$=3x(-xy-1+3y ^{2})$

Check:

so, 3x and $(-xy-1+3y ^{2})$ are two factors of the given expression. If both multiplied like below;

$3x (-xy-1+3y ^{2})= 3x.(-xy)-3x.1+3x.3y ^{2}$ $=-3x2y-3x+9xy ^{2}$

i-e same original expression we get.
