Expansion : [tex](x+1)(x+9) = x(x+9) + 1(x+9) = x^{2} +9x + x + 9[/tex]
Simplify : [tex]x^{2} +10x + 9[/tex]

Answer:

[tex]\huge\boxed{ \bf\:x^{2} + 10x + 9}[/tex]

Step-by-step explanation:

[tex](x + 1)(x+9)[/tex]

Let's expand it at first.

[tex](x + 1)(x + 9)\\= x (x + 9) + 1 (x + 9)\\= x^{2} + 9x + x + 9[/tex]

Now, simplify it.

[tex]x^{2} + x + x + 9\\= \boxed{ x^{2} + 10x + 9}[/tex]
