Question

Identify the terms and like terms in the expression. x² - 3x + 4 + 2x² - x - 12. Thank you to anyone who helps, I appreciate it :)

Answer 1

Given:

The expression is:

`x^2-3x+4+2x^2-x-12`

To find:

The terms and like terms in the expression.

Solution:

Terms: Variables, constants and product of variable and constants are known as terms which are separated by addition sign "+".

Like terms: The terms which contain same variables with same power are known as like terms.

The given expression is:

`x^2-3x+4+2x^2-x-12`

It can be rewritten as:

`x^2+(-3x)+4+2x^2+(-x)+(-12)`

Terms are
`x^2,-3x,4,2x^2,-x,-12`.

Like terms are
`x^2,2x^2` and
`-3x,-x` and
`4,-12`.
