Given $\"%28x%2B5%29%28x%2B2%29\"$ \r
\n" ); document.write( "\n" ); document.write( "To do these 'in your head', you need to look at the coefficients on the x terms. In this case, both are equal to 1. So, the resulting coefficient on the $\"x%5E2\"$ term will be $\"1%2A1\"$ = 1\r
\n" ); document.write( "\n" ); document.write( "Now let's do the constant term:
\n" ); document.write( "By looking at the two constants (5 and 2), you can see the last term will be the product of $\"2%2A5\"$ = 10.\r
\n" ); document.write( "\n" ); document.write( "The hardest part if figuring out what the middle term, the $\"x\"$ term will be. For that you need to realize that coefficient is a sum or difference of two products. In our case, since both terms have a + sign in them, the resulting x term will be a sum. It is the sum of $\"1%2A5\"$ + $\"1%2A2\"$ = $\"5%2B2\"$ = 7.\r
\n" ); document.write( "\n" ); document.write( "So the answer is $\"x%5E2+%2B+7x+%2B+10\"$ \r
