Complete the trinomial so it is a perfect square. x^2 + ___+ 64
\n" ); document.write( "Thanks a lot!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since + 64 (c) is derived from \"%28b%2F2%29%5E2\", then we can say that: \"%28b%2F2%29%5E2+=+64\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"b%5E2%2F4+=+64\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"b%5E2+=+256\" ------- Cross-multiplying\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"b+=+sqrt%28256%29\", or \"16\", making the middle term of the trinomial, \"highlight_green%2816x%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The trinomial is therefore: \"x%5E2+%2B+16x+%2B+64\", or \"%28x+%2B+8%29%5E2\"\r
