$e^{2x}-2e^xe^{-x}+e^{-2x}-\left(e^x+e^{-x}\right)^2$
Learn how to solve integral calculus problems step by step online. Find the break even points of the expression (e^x-e^(-x))^2-(e^x+e^(-x))^2. Expand \left(e^x-e^{-x}\right)^2. Apply the exponent property of product of powers: x^a\cdot x^b=x^{a+b}. Cancel like terms x and -x. Any expression (except 0 and \infty) to the power of 0 is equal to 1.
