Question

the square of the sum of 5 and a number

Answer 1

(x+5)^2 will be the answer

Answer 2

Given:

To find the square of the sum of 5 and a number.

Solution:

Assume that the number is $x$,

Therefore,

$\[\begin{array}{l} \Rightarrow {\left( {x + 5} \right)^2}\\ \Rightarrow {x^2} + 25 + 2 \times 5 \times x\\ \Rightarrow {x^2} + 10x + 25\end{array}\]$

Hence  the square of the sum of 5 and a number is $\[{x^2} + 10x + 25\]$.
