You can put this solution on YOUR website!
these are always fun to do...pick 2 of the four terms and factorise those, then do the other 2 terms. Hopefully you will then have 2 sets of factors that have a common term. This is the whole point of these questions...the solution should be there, just need to hunt for it...
1. kj-60%2B10k-6j becomes
j%28k-6%29+%2B+10%28k-6%29
%28j%2B10%29%28k-6%29
2. gh%2B12h%2B3h%5E2%2B4g becomes
g%28h%2B4%29+%2B+3h%28h%2B4%29
%28g%2B3h%29%28h%2B4%29
3. 2z%5E2%2B12x%2B3z%2B8xz becomes
z%282z%2B3%29+%2B+4x%282z%2B3%29
%28z%2B4x%29%282z%2B3%29
