$e^{2x}-2e^xe^{-x}+e^{-2x}-\left(e^x+e^{-x}\right)^2$
Learn how to solve exponential equations problems step by step online. Expand the expression (e^x-e^(-x))^2-(e^x+e^(-x))^2. Expand \left(e^x-e^{-x}\right)^2. When multiplying exponents with same base we can add the exponents. Cancel like terms x and -x. Calculate the power e^{0}.
