Question

[HOW THIS EQUAL?]
-2(e^t)(e^-t)+e^(-2t)+4=e^(2t)+2+e^(-2t)

Answer 1

\[-2e^te^{-t}+e^{-2t}+4=e ^{2t}+2+e ^{-2t}\]

Answer 2

how do i simply simplify this....?

Answer 3

\[-2e^te^{-t}+e^{-2t}+4=e ^{2t}+2+e ^{-2t}\]

Answer 4

wait sorry i put wrong..

Answer 5

-2e^te^{-t}+e^{-2t}+4= 2+e ^{-2t}

Answer 6

\[-2e^te^{-t}+e^{-2t}+4= 2+e ^{-2t}\]

Answer 7

wait lemme close and re open it
