Let the number = x
The sum of five times a number and 2
Since, the number = x
five times the number = 5 * x
Fivetimes the number = 5x
The sum of five times a number and 2 = 5x + 2
[tex]\begin{gathered} \text{Taking the square} \\ \text{The square of the sum of five times a number and two is} \\ (5x+2)^2 \\ \text{Thr}ee\text{ more than the square of the sum of five times a number and two} \\ \text{More than means addition } \\ =(5x+2)^2\text{ + 3} \\ \text{The answer is (5x + 2)}^2\text{ + 3} \end{gathered}[/tex]
