1 0
0 -1 in brackets look i always take the points (1,0) and (0,1) then do transformation on these so reflection in x axis so (1,0) remains (1,0) so i write vertically on the left side 1
0
then transform the other point 0,1 which becomes 0,-1 so i write this on the right side.. so the matrix becomes
1 0
0 -1
Note: always perfom 1st transformation on 1,0 then on 0,1 and set the vertically

it is like make the denominator equal so you multiply it with x+4 both now move the the denominator which is x^2-16 to the other side and so on....
