Question

which of the following expressions are p
olynomials. if not give reason a). 1/x(x+5).
b) ✓5x²+✓3x+✓2
​

Answer 1

Answer:

Step-by-step explanation:

Variables in Polynomials can have only positive integers as exponents

$\frac{1(x+5)}{x}$ This polynomial has $x^{-1}$ so is not a polynomial

whereas (b)$\sqrt{5}x^2+\sqrt{3}x+2$ has only positive integers as exponent of variable hence is a polynomial
