the quadratic equation whose roots are $\"x%5B1%5D=-4\"$ and $\"x%5B2%5D=1\"$ and who's leading coefficient is $\"a=5\"$ will be:\r
\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=a%28x-x%5B1%5D%29%28x-x%5B2%5D%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=5%28x-%28-4%29%29%28x-1%29\"$
\n" ); document.write( " $\"f%28x%29=5%28x%2B4%29%28x-1%29\"$
\n" ); document.write( " $\"f%28x%29=5%28x%5E2+%2B+3x+-+4%29\"$
\n" ); document.write( " $\"f%28x%29=5x%5E2+%2B+15x+-+20\"$ => answer\r
