quick doubt in c3

(1/1)

7ooD:
write the following in simplest form involving only one trigonometric function

tanA/(sec^2A)-2

i tried to solve it as following

(sec^2A)=tan^2A+1

tan^2A+1-2

tan^2A-1

-(-tan^2+1)

tanA/-(-tan^2+1)

2tanA/-(-tan^2+1)

-2(1/2tan2A)

-tan2A

in the answers it says -1/2tan2a not -tan2a as i solved above wat did i do wrong

Saladin:
