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

Answer and explanation

Correct answer: 2

While removing the brackets, the sign of every term in the second polynomial changes: p(x)=x^5-3x^2+2-x^5+x^2=-2x^2+2. The highest power of x is 2, so the degree of the polynomial is 2. It is not 5 because the x^5 terms cancel each other. Exam tip: When subtracting a polynomial in brackets, change the signs of all its terms.
