next time if you want to use expression like  a power 2 write it as ( a^2)

LHS : (1 - tanq)^2  + (1 + tan q)^2 
apply ( a+b)^2 and (a-b)^2 property
1 - 2tanq + tan^2 q + (1 + 2tanq + tan^2 q)
1 - 2tanq + tan^2 q + 1 + 2tanq + tan^2 q
1 + 1  + 2tan^2 q
2 + 2tan^2 q 
2( 1 + tan^2 q)
2(sec^2 q)  [ tan^2Θ + 1 = sec^2Θ]
