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

The algebraic expression  $3x+2y+6$  is a

• Monomial

• Binomial

• Trinomial

• None of the above

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

• $7x\ ,\ 7y$

• 
  $7x,\ 9x$
  

• $7x,\ 7x^2$
  

• $7x,$ $7xy$
  

If we subtract  $4a–7ab+3b+12$  from  $12a–9ab+5b–3$  then the answer is:

• 
  

  $8a+2ab+2b+15$

• $8a+2ab+2b-15$

• $8a-2ab+2b-15$

• $8a-2ab-2b-15$

2x + 5x - 4 + 1

• 7x -3

• 10x - 3

• 4x

4( x + 1 ) - 2x

• 4x + 5

• 2x -4

• 2x + 4

2( x - 1) + 3 ( 2x + 1)

• 0

• 9x - 4

• 8x + 1

 $3x^3+x^2-2x^{3\ }+2x^2-1$  

•  $x^3+3x^2-1$  

•  $x^{3\ }+x^{2\ }-1$  

•  $4x^5-1$  

the product of a number and 9
