Question

Factorise
1
12xy - 18x²y

​

Answer 1

Answer:

$12xy - 18 {x}^{2} y \\ = 6xy(2 - 3x)$

Answer 2

Question :

Factorise : 12xy - 18x²y

Answer :

This can be done in two ways :

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

➳ $12xy - 18x^2y$

➳ ${-18x^2y + 12xy}$

✯ $\boxed{(-)×(+)=(-)}$

✯ $\boxed{Subtracting\:18 - 12}$

➳ $6xy$

➳ $6xy\:({-x^2 + x}+{y+y})$

➳ $\bold{6xy{(-3x + 2)}}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

➳ $12xy - 18x^2y$

✯ $\boxed{Extract\:common\:factor}$

➳ $6xy$

➳ $6xy\:({-x^2 + x}+{y+y})$

➳ $\bold{6xy{(-3x + 2)}}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Some Points to Remember :

✎ $\boxed{(-)×(-)=(+)}$

✎ $\boxed{(+)×(-)=(-)}$

✎ $\boxed{(-)×(+)=(-)}$

✎ $\boxed{(+)×(+)=(-)}$

So It's Done !!
