If (q(x)=(k-1)^2x^{10}+(k^2-1)x^6+4x^2) and (k=1), what is the degree of (q(x))?

Answer and explanation

Correct answer: 2

On substituting k=1, we get (k-1)^2=0 and k^2-1=0. Hence the coefficients of the x^{10} and x^6 terms become zero, leaving q(x)=4x^2. The degree of a polynomial is the highest exponent with a non-zero coefficient, so its degree is 2. Option 0 would apply if the polynomial reduced to a non-zero constant. Exam tip: substitute the parameter first, discard zero-coefficient terms, and then identify the highest remaining exponent.
