Can somebody help me on factorising i know how to expand brackets but i find factorising harder.
36X(I dont know how to get the Algebra x) -30y-42 z
and 2cd-3de+4d
Thank You so much and have nice day :)

Factoring is all about finding common members of all terms. The only commonality to the first one are the numbers, so try to pull some out:
36x -30y-42z
6(6x-5y-7x)
For the second, the only one member common to each term is d, so:
2cd-3de+4d
d(2c-3e+4)
I hope that helps!

36x - 30y - 42z =
(6*6)x - (6*5)y - (6*7)z =
6 * (6x - 5y - 7z)
2cd - 3de + 4d =
d * (2c -3e + 4)

6(6x-5y-7z)
d(2c-3e +4)
