i have an exponential problem that i could not solve. [tex] (b-a-2)e^b + (b-a)e^a [/tex] where a and b are constant. Is it the same as [tex] b^2 -2e^b + 6b - a^2 + 2e^a - 6a [/tex] ? Hope that someone kind could spend some time helping me and list down the steps for me. If they are not equal can you pls tell me too? Thank you!
