Question

factarise 1) 2x+4y 2)18mn+10mnp 3)6ab+12ab
4)-xy-ay 5)6x^3-9x^2+3x​

Answer 1

Answer:

1. Given : 2x+4y−8xy−1

We can further write it as  

2x+4y−8xy−1=2x−1−8xy+4y

By taking common terms out  

2x+4y−8xy−1=(2x−1)−4y(2x−1)

So we get,

2x+4y−8xy−1=(2x−1)(1−4y)

2. We have,

18mn+10mnp

Factoring 2mn out,  

=2mn(9+5p)

∴18mn+10mnp=2mn(9+5p)
