\n" ); document.write( "\n" ); document.write( "a). \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B25=+%28x%2B5%29%28x%2B5%29\" => this is not equal,
\n" ); document.write( "\"x%5E2%2B5%5E2%3C%3E+%28x%2B5%29%28x%2B5%29\" because \"x%5E2%2B5%5E2\" is the sum of squares and the rule for factoring the sum of squares:\"a%5E2%2Bb%5E2\" can be factorized as \"%28a%2Bib%29%28a-ib%29\"
\n" ); document.write( "if your factors were \"%28x-5i%29%28x%2B5i%29\", it would work because \"x%5E2%2B25=%28x-5i%29%28x%2B5i%29\"
\n" ); document.write( "
\n" ); document.write( " b). \r
\n" ); document.write( "\n" ); document.write( "\"10x%5E3%2B15x%5E2%2B5x+=+5x%282x%5E2%2B3x%29+\"....missing one more term in parentheses\r
\n" ); document.write( "\n" ); document.write( "\"10x%5E3%2B15x%5E2%2B5x+=+5x%282x%5E2%2B3x%2B1%29+\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " c). \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2-2x%2B24=+%28x-6%29%28x%2B4%29+\"=> multiply \"%28x-6%29%28x%2B4%29+\"=>\"x%5E2%2B4x-6x-24=x%5E2-2x-24+\"; as you can see \"x%5E2-2x%2B24%3C%3E+x%5E2-2x-24+\"\r
\n" ); document.write( "\n" ); document.write( "; so, here we will have complex solutions again\r
