An algebraic expression that contains only one term is called

• Monomial

• Binomial

• Trinomial

• None of the above

 $5x\ +\ 6y$   is a 

• Monomial

• Binomial

• Trinomial

• None of the above

A polynomial contains _______ number of terms:

• One

• Two

• Three

• Any

In which of the following, the two expressions are like terms?

• $7x\ ,\ 7y$

• 
  $7x,\ 9x$
  

• $7x,\ 7x^2$
  

• $7x,$ $7xy$
  

If we add $7xy+5yz–3zx$   $4yz+9zx–4y$  and

 and  $–3xz+5x–2xy$  then the answer is:

•  $5xy+9yz+3zx+5x–4y$  
  

•  $5xy–9yz+3zx–5x–4y$  
  

•  $5xy+10yz+3zx+15x–4y$  
  

•  $5xy+10yz+3zx+5x–6y$
