$-e^{2x}=e^x+\left(-1-e^x\right)e^x$
Learn how to solve rational equations problems step by step online. Solve the rational equation (-e^(2x))/(1+e^x)=(e^x)/(1+e^x)-e^x. Multiply both sides of the equation by 1+e^x. Multiply both sides of the equation by -1. Cancel like terms -e^x and e^x. If the bases are the same, then the exponents must be equal to each other.
