Question

Identify the like expressions , 14x, 3x2 , 1, 5x, x2 , -9x2 , xy, - 3xy​

Answer 1

Answer:

Like terms are,

i) $14x$ and $5x$.

ii) $3x^{2} ,x^{2}$ and $-9x^{2}$.

iii) $xy$ and $-3xy$.

iv) $1$ is a constant term.

Step-by-step explanation:

Given : The terms are $14x, 3x^{2} ,1, 5x,x^{2} ,-9x^{2} ,xy,-3xy$.

To find : Identify the like terms.

Solution :

• The given terms are $14x, 3x^{2} ,1, 5x,x^{2} ,-9x^{2} ,xy,-3xy$.
• We have to find the like terms.
• Like terms are the terms with same variable with same exponential powers. Their coefficient can be different.

        Ex. $x^{2}$ and $4x^{2}$ are like terms.

• Here, like terms are,

      i) $14x$ and $5x$.

      ii) $3x^{2} ,x^{2}$ and $-9x^{2}$.

      iii) $xy$ and $-3xy$.

      iv) $1$ is a constant term.
