Hey, this is one other question I wouldn't mind help with if that's alright
1) Factorise \(\displaystyle 8x^{2}y^{3}z + 2xyz - 4^{3}yz^{2} \)
I ended up with \(\displaystyle 2xyz\left ( 3xy^{2} - 1 + 2x^{2}z \right ) \)
2) Factorise fully into two brackets \(\displaystyle bx - 4y + by - 4x \)
I swapped the terms around and got \(\displaystyle bx + by - 4y - 4x \)
and finished with \(\displaystyle b\left ( x + y \right ) - 4\left ( y - x \right ) \)
Thanks, hoping I can do the rest off my own back
