Question

A friend rewrote the expression 5(x + 2) as 5x + 2. Write a few sentences explaining the error. Then, rewrite the expression 5(x + 2) correctly.

Answer 1

If an expression is shown as 5(x+2) the numbers inside the parenthesis must both be multiplied by the number outside. Only x was multiple. The correct rewritten expression would be 5x+10
