Write the degree of each of the following polynomials:

(i) 5x³ + 4x² +7x

(ii) 4 - y²

(iii) 5t - $\sqrt{7}$

(iv) 3

Classify the following as linear, quadratic and cubic polynomials:

(i) x² + x

(ii) x - x³

(iii) y + y² + 4

(iv) 1 + x

(v) 3t

(vi) r²

(vii) 7x³

Find p(0), p(1) and p(2) for each of the following polynomials:

(i) p(y) = y² - y + 1

(ii) p(t) = 2 + t + 2t² - t³

(iii) p(x) = x³

(iv) p(x) = (x - 1) (x + 1)

Verify whether the following are zeroes of the polynomial, indicated against them.

(i) p(x) = 3x + 1, x = $-\dfrac{1}{3}$

(ii) p(x) = 5x - π, x = $\dfrac{4}{5}$

(iii) p(x) = x² - 1, x = 1, -1

(iv) p(x) = (x + 1)(x - 2), x = -1, 2

(v) p(x) = x², x = 0

(vi) p(x) = lx + m, x = $-\dfrac{m}{l}$

(vii) p(x) = 3x² - 1, x = $-\Big(\dfrac{1}{\sqrt{3}}\Big)$, $\Big(\dfrac{2}{\sqrt{3}}\Big)$

(viii) p(x) = 2x + 1, x = $\dfrac{1}{2}$
