Step-by-step explanation/ Answer:
These expression are polynomials.
polynomials- A polynomial is an expression that consist with variables and coefficients that involves only subtraction,addition,division,or multiplication.
Monomial is a type of polynomial. Monomial consist of one term.
example of a monomial is down below.....
Why are the following expressions not monomial?
3/h is not a monomial because a variable is being divided if you put into fraction form the variable is in the denominator. which makes it not a monomial.
ab-1 has a negative exponent so this is incorrect
x+2w this more than one variable so its not one term. therefore its not a monomial.
3cdx has 3 variable being multiplied by each other so it would look like this
3*c*d*x this is not a monomial because its more than one term.
Which expressions are monomial?
b+2b+2 has 3 terms so this is a trinomial not a monomial.
(x-2x)2 we need to simplify to see if this is a monomial
2x*2=4x
x*2=2x
2x-4x= -2x
-2x is a monomial
-4+6 is not a monomial or a polynomial because it doesnt have a variable.
rs/t is not a polynomial becuase a variable is being divided and cannot be simplifed
36x2yz3 is a monomial since its just one term.
