Answer:

[tex]2x^{2} + 8x + 10[/tex]

Step-by-step explanation:

Split these into two separate squares.

One has side lengths of x + 3, and the other has side lengths of x + 1.

We'll solve the first square first.

Here is the expression we want to use:

[tex](x+3)[/tex] * [tex](x+3)[/tex]

Use FOIL (first, outer, inner, last).

[tex]x^{2} + 3x + 3x + 9[/tex]

Simplify.

[tex]x^{2} + 6x +9[/tex]

Time for the second square!

This goes similarly to the first one, so I'll omit any words and you can follow along with the math.

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

[tex]x^{2} + x + x +1[/tex]

[tex]x^{2} + 2x + 1[/tex]

Now, we'll add them together.

[tex]x^{2} + 6x +9[/tex] [tex]+[/tex] [tex]x^{2} + 2x + 1[/tex]

Combine like terms.

[tex]2x^{2} + 8x + 10[/tex]

And we're done!
