Answer:

The right algebraic expression is 2x - 1

Explanation:

Let us change the given phrase from words to mathematics expression

  • Twice means multiply by 2
  • Less than a number by a given value means the number minus the value

In our question, the phrase is " One less than twice a number "

To change it to an algebraic expression

→ Assume that the number is x

Twice a number means 2 × x = 2x

One less than twice the number means 2x - 1

∴ The algebraic expression is " 2x - 1 "

→ The error in the given expression is

  • Translate twice a number to x²
  • x² is square a number

The right algebraic expression is 2x - 1
