You can put this solution on YOUR website!
Zero is just another name for root
\n" ); document.write( "You are given:
\n" ); document.write( " $\"+x+=+-3+\"$
\n" ); document.write( " $\"+x+=+1+\"$
\n" ); document.write( "Or, what is the same thing:
\n" ); document.write( " $\"+x+%2B+3++=+0+\"$
\n" ); document.write( " $\"+x+-+1+=+0+\"$
\n" ); document.write( "---------------
\n" ); document.write( "Multiplying these:
\n" ); document.write( " $\"+%28+x%2B3+%29%2A%28+x-1+%29+=+0+\"$
\n" ); document.write( " $\"+x%5E2+%2B+3x+-+x+-+3+=+0+\"$
\n" ); document.write( " $\"+x%5E2+%2B+2x+-+3+=+0+\"$
\n" ); document.write( "You are asked to sketch the function
\n" ); document.write( " $\"+f%28x%29+=+x%5E2+%2B+2x+-+3+\"$
