You can put this solution on YOUR website!
-6x(x+1)+4=16 first, get rid of parens (distributive law)
\n" ); document.write( "-6x^2-6x+4=16 next, subtreact 16 from both sides
\n" ); document.write( "-6x^2-6x+4-16=16-16 Now, collect like terms
\n" ); document.write( "-6x^2-6x-12=0 divide each term by -6
\n" ); document.write( "x^2+x+2=0-------------------quadratic in standard form\r
\n" ); document.write( "\n" ); document.write( "We'll solve using the quadratic formula:
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%28-1+%2B-+sqrt%28+1%5E2-4%2A1%2A2+%29%29%2F%282%2A1%29+\"
\n" ); document.write( "\"x+=+%28-1+%2B-+sqrt%28+1-8+%29%29%2F%282%29+\"
\n" ); document.write( "\"x+=+%28-1+%2B-+sqrt%28-7+%29%29%2F%282%29+\"
\n" ); document.write( "\"x+=+%28-1+%2B-+sqrt%28%28-1%29%287+%29%29%29%2F%282%29+\"
\n" ); document.write( "\"x+=+%28-1+%2B-+%28i%29sqrt%287+%29%29%2F%282%29+\". So:
\n" ); document.write( "\"x+=+%28-1+%2B+%28i%29sqrt%287+%29%29%2F%282%29+\"
\n" ); document.write( "and
\n" ); document.write( "\"x+=+%28-1+-+%28i%29sqrt%287+%29%29%2F%282%29+\". \r
