Question

Write the following statement using symbolic language.

The sum of a number squared and three less than twice the number is 129.

Answer 1

Answer:
`x^2 +2x-3=129`

Explanation:

Let the number be
`x`.

'A number squared' means
`x^2`.

'Twice the number' means
`2x`, and 'three less' means to subtract 3, giving
`2x-3`.

'The sum' means to add, giving
`x^2 +2x-3=129`.
