An algebraic expression in which the variables involved have only non-negative integral
powers is called a polynomial.
i) 3x²+√2 is a polynomial
ii) 2x+7/2 is a polynomial
iii) 7√y + 2y is not a polynomial.
because the first term √y is a
term with an exponent that is not a non-negative integer ( i.e.1/2).
iv) 4 cube root x + 2x +2 is not a polynomial. Because the first term cube root x is a
term with an exponent that is not a non-negative integer ( i.e.1/3).
v) 3/y + y² is not a polynomial.Because the first term 3/y has a negative exponent (i.e .,-1) .
because the y cannot be in terms of minus it should always be a whole number
