By inspection, I see that
\n" ); document.write( " $\"+x%5E2+%2B+16x+%2B+64+=+%28+x+%2B+8+%29%5E2+\"$
\n" ); document.write( "To find x-intercepts,
\n" ); document.write( " $\"+f%28x%29+=+0+\"$
\n" ); document.write( " $\"+%28+x+%2B+8+%29%5E2+=+0+\"$
\n" ); document.write( "Take the square root of bpth sides
\n" ); document.write( " $\"+x+%2B+8+=+0+\"$
\n" ); document.write( " $\"+x+=+-8+\"$
\n" ); document.write( "The x-intercept is a \"double root\" at (-8,0)
