Question 18367
first, you make something that looks like this.
{{{(x+_)(x+_)}}}
Take the last number of the equation, 1.
What are factors of that numbers, in other words, what times what equals 1?
Obviously {{{1*1}}}
Then just plug 1 and 1 into the empty spaces.
{{{(x+1)(x+1)}}}
since they are the same, you can stack them.
{{{(x+1)^2}}}
Hope this helps!
