Answer:
[tex]\huge \boxed{(x+7)^2 }[/tex]
Step-by-step explanation:
The quantity x + 7 is squared.
[tex](x+7)^2[/tex]
Expand the brackets and simplify the expression.
[tex](x+7)(x+7)[/tex]
[tex]x(x+7)+7(x+7)[/tex]
[tex]x^2 +7x+7x+49[/tex]
[tex]x^2 +14x+49[/tex]
We can leave the expression in factored form.
