Answer:
x(x²+4x)
Step-by-step explanation:
Quadratic functions only have variables up to an exponent of 2.
This expression, if factored out, would have a variable with an exponent of 3.
So, it can't be a quadratic.
Factoring out and dividing out all the other ones would give expressions that only have variables up to 2.
