If (p(x)=x^2(x^3+x)-x^5-x^3+6), what is the degree of (p(x))?

Answer and explanation

Correct answer: 0

First expand: \(x^2(x^3+x)=x^5+x^3\). Therefore, \(p(x)=x^5+x^3-x^5-x^3+6=6\). A non-zero constant polynomial such as \(6\) has degree \(0\), so the correct answer is 0. Option 5 is tempting because it appears before simplification, but the highest-degree terms cancel. Exam tip: simplify a polynomial and combine like terms before finding its degree.
