Question

Identify variable co efficient and constant in each algebric expression(i) x²+3

Answer 1

Answer: below

Explanation:

Our task is to identify the variable, the coefficient, and the constant in the following expression:
`x^2+3`.

First, let's take a look at what these terms mean.

A variable is a letter that represents a number; for instance, in the expression z + 7, the variable is z.

A coefficient is the number before a variable; if you don't see a number, then the coefficient is 1. For instance, in z + 7, there's no number in front of z, so that means that the coefficient of z is 1.

A constant is simply a number that doesn't have variables multiplied by it. In the expression z + 7, the constant is 7.

--------

So now let's take a look at our expression:
`x^2+3`.

• the variable is x
• the coefficient is 1
• the constant is 3

we're done :)
