Know that -a^2 means -1 x a^2 and not -a x -a. The reason is that -a^2 has its coefficient as -1 Therefore -a x -a = a^2 and and not -a^2. This symbol ^ implies exponent.

Thank for explaining this exponential function here, I completely understand the equation. Here coefficient is different thing and variable is different.
