\n" ); document.write( "Factor \"x%5E2-16x%2B60\"

\n" ); document.write( "It will factor into the product of two linear polynomials.

\n" ); document.write( "The positive constant (\"+60\") tells us that the signs in both factors are the same; then the negative linear term (\"-16x\") tells us the signs are both negative.

\n" ); document.write( "So the polynomial factors in the form

\n" ); document.write( "\"x%5E2-16x%2B60+=+%28x-a%29%28x-b%29\"

\n" ); document.write( "With the given coefficients -16 and +60, we need two integers a and b with a sum of 16 and a product of 60. Quick mental arithmetic tells us the two numbers are 6 and 10. So

\n" ); document.write( "\"x%5E2-16x%2B60+=+%28x-6%29%28x-10%29\"

\n" ); document.write( "
