Answer» it is wrong Step-by-step explanation: Given EQUATION is : = > (TAN theta + 2)(2 tan theta + 1) = > (2tan^2 theta + tantheta + 4tantheta + 2) = > (2(sec^2theta - 1) + 5tantheta + 2) = > (2sec^2 theta - 2 + 5tantheta + 2) = > (2sec^2theta + 5tantheta). Therefore the final answer will be 2sec^2theta + 5tantheta. PLEASE MAKE ME AS BRAINLIST |
