1: 16n²-8n-5(2n-1)²
2: (x-2)(x+3)-6x
3: y^(6)-1
4: 3p²-7p-6
5: (x+1)²-(y+1)²
Fast thx
I have not done the rest but I will give you hints on where I would start.
2) Try expanding and simplifying first and see if that helps
3) Think of it as ((y^3)^2-1^2) and go from there.
4) standard factorising
5) It is a difference of 2 squares.
you have a go and get back with what you have found/done. We can take it from there. :)
$$\\1)\\\\
8n(2n-1)-5(2n-1)(2n-1)\\
=8n(2n-1)+(-10n+5)(2n-1)\\
=(8n-10n+5)(2n-1)\\
=(-2n+5)(2n-1)\\
=(5-2n)(2n-1)\\$$
Have you tried to do these for yourself?
