Question

Using the expression 5x2 + 7, match the following items. 1. 2 variable 2. 5 coefficient 3. 7 exponent 4. x constant

Answer 1

5x^2 + 7

the coefficient is 5
the variable is x
the exponent is 2
the constant is 7

Answer 2

Variable:
`x`

Coefficient: 5

Exponent: 2

Constant: 7

Explanation:

We have been given an expression
`5x^2+7`. We are asked to match each term with correct option.

Variable: We know that variable is a value that is not consistent. It can change. The variables are mostly defined as letters like a,b ,c, x or y.

We can see that in our given expression the variable is
`x`.

Coefficient: We know that a coefficient is a quantity multiplied by the variable. We can see that 5 is multiplied by x, therefore, 5 is coefficient.

Exponent: Exponent means a quantity or variable raised to a power. We can see that x is raised to second power, therefore, exponent is 2.

Constant: A quantity which remains same or which never changes.

We can see that 7 is constant for our given expression a sit remains same.
