If (p(x)=x^2(x^2-1)-x^4+x^2+5), what is the degree of (p(x))?

Answer and explanation

Correct answer: 0

First simplify the expression: \(x^2(x^2-1)=x^4-x^2\). Therefore, \(p(x)=x^4-x^2-x^4+x^2+5=5\). This is a non-zero constant polynomial, so its degree is \(0\). Option 4 results from noticing the highest power before simplification, but those terms cancel out. Exam tip: always simplify a polynomial completely before finding its degree.
