Question

Which of the following are like terms? 12x -8 3x2 15x –x x³

Answer 1

Answer:

12x, 15x and -x

Step-by-step explanation:

The given terms are: 12x -8, $3x^2$, 15x -x, $x^3$

First let's see what a like term is.

The like terms are the terms that have the same variables and the exponents number. The coefficients of the variables may be differ. For instance, 2x, -3x, -x are the like terms

ii) $3xy^2 and -5xy^2$ are the like terms.

You can see the variables and their exponents are the same in the like terms.

Now let's move to our question. We need to identify the like terms from the given terms.

12x -8, $3x^2$, 15x -x, $x^3$

Here the like terms are: 12x, 15x and -x.

We can add or subtract only the like terms.

Answer 2

Answer:

Like terms are:

12x, -x & 15x are like terms.

Step-by-step explanation:

Like terms: In algebra math, like terms are those terms that have the same variables and exponents. The coefficients of the variable may be different.

For example: 3x^2 & 4x^2 are like terms.

Here variable x^2 is same. So, they are like terms.

In this question:

12x - 8 , 3x², 15x - x, x³

Here we see that, like terms are 12x, 15x & -x.

That's the final answer.

I hope it will help you.
