Classify the following as a constant , linear , quadratic and cubic polynomials:
(i)2−x2+x3(ii)3x3(iii)5t−√7(iv)4−5y2
(v)3(vi)2+x(vii)y3−y(viii)1+x+x
(ix)t2(x)√2x−1
(i) 2−x2+x3 → cubic
(ii) 3x3 → cubic
(iii) 3t−√7 → linear
(iv) 4−5y2 → quadratic
(v) 3 → constant
(vi) 2+x → linear
(vii) y2−y → cubic
(viii) 1+x+x → linear
(ix) t2 → quadratic
(x) √2x−1 → linear
