>>1088430>-6x^6Kek that's not even the right wrong answer. -6x^2 would at least be logically consistent (subtracting the exponents)
Different powers of the same base cannot be added. Imagine if X=5. You can't just add x^2 + x^3 = 2x^5 anymore than you can add 5^2 + 5^3 = 10^5. It makes no sense. Treat x and x^2 almost like different variables.
