simplify x^4 5x^3 11x^2

To CogitoEroCogitoSum, there seems to be a problem with the plus symbol for some reason. I don't know why, but I've noticed fairly consistently in the last day or two that plus signs have been concatenated out. There's no need to pass judgement on the poor askers.

As for the question at hand, obviously you want:

x^4 + 5x^3 + 11x^2

This can't exactly be simplified per se, but it can be factorised:

x^2(x^2 + 5x + 11)

The quadratic can't actually be factorised, so this is it's most factorised form.

I wont help. I have no sympathy for someone that is too apathetic to even copy their problem down correctly

x^4 + 5x^3 + 11x^2
= x^2(x^2 + 5x + 11)

1) Factor out a GCF.
x^2(x^2×5x×11)
2) Can you factor further? In this case, no. You have your final answer.

If it is a multiplication as you have written tnan answer is 55x^9
since you multiply the numbers and multiplying the powers you add exposants
If it is an addition
than x^2*(x^2+5x+11)
