Answer 1

A polynomial is an expression that can consist in constants, variables and exponent. It can be combined in using addition, subtraction, division, but
NO DIVISION BY A VARIABLE and exponents SHOULD BE INTEGER:


A) 4x³ -2/x: WRONG (division by a variable)

B) 2y³ + 5y² - 5y : YES POLYNOMIAL

C) 3y³- √4y: WRONG (the exponent of 4y is (1/2)

D) - xy√6: YES POLYNOMIAL (√6 is a constant)
