Question

Write an algebraic expression to represents the verbal expression: the difference between the product of 4 and a number and the square of the number

Answer 1

`4n-n^2`

Explanation:

I use 'n' as the unknown value, but you can use any letter you want as the variable.

The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.

The square of the number would be n². Squaring a number is multiplying a number by itself.

The phrase 'difference between...' means subtraction.

Putting it together:

"The difference between the product of 4 and a number and the square of the number" would be:

`4n-n^2`

Hope this helps.
