Answer»

i) 5x² + x – 7 : degree 2 hence quadratic polynomial.

ii) x – x³ , : degree 3 hence cubic polynomial.

iii) x² + x + 4 : degree 2 hence quadratic polynomial.

iv) x – 1 : degree 1 hence linear polynomial.

v) 3p : degree 1 hence linear polynomial.

vi) πr² : degree 2 hence quadratic polynomial.
