iv. VX + a.​

Answer 1

i dont think this is right

Answer 2

Answer:

(i) x2 + 2x-2 The given expression is not a polynomial. Because a polynomial does not contain any negative powers or fractions. (ii) √(ax) + x2 – x3 The given expression is a polynomial. Because the polynomial has positive powers. (iii) 3y3 – √5y + 9 The given expression is a polynomial. Because the polynomial has positive powers. (iv) ax1/2 + ax + 9x2 + 4 The given expression is not a polynomial. Because a polynomial does not contain any negative powers or fractions. (v) 3x-3 + 2x-1 + 4x + 5 The given expression is not a polynomial.
