Question

How many variable terms are in the expression 3x³y + 5xz − 4y + x − z + 9

Answer 1

There are 6
1. 3x^3y
2. 5xz
3. -4y
4. x
5. -z
6. 9

Answer 2

Answer: 6

Step-by-step explanation:

In any algebraic expression a term could be a variable(a,b,c,...), or a constant (numerical value) or  a product of variables and a constant.

For example : In expression $5x^2-7xy+4c-4$ , there are 4 terms : $5x^2,\ -7xy,\ 4c\ ,\ -4$

Let's take one more example :  $3y+2x-7xy^2$

In this expression there are only 3 terms , that are $3y,\ 2x,\ -7xy^2$

The given expression : $3x^3y + 5xz -4y + x -z + 9$

There are total 6  variable terms , that are :

$3x^3y ,\ 5xz,\ -4y ,\ x,\ -z ,\ 9$

Hence, the correct answer is : 6
