In calculus, i need to use l'hopital's rule tofigure out the derivative of lim (x^2)(e^-x)x-> 0can someone explain how to use the rule on a non fractional function?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
