Factorise the following a) 8x + 6y b) 7xy + 3xzy c)5xyz - 20x^2y^2z
In order to factorise successfully, we have found the highest common factor for part a,b and c (the highest number that can be divided exactly into each of the terms) and placed these outside of the brackets
a) 2 (4x+3y)
b) xy (7 + 3z)
c) 5xyz ( 1- 4xy)
hint: for part b the order of the letters does not matter!
