Solve for m:
\n" ); document.write( " $\"4m%5E2-28m%2B49+=+0\"$ Factor the quadratic equation.
\n" ); document.write( " $\"%282m-7%29%282m-7%29+=+0\"$ Apply the zero product rule:
\n" ); document.write( " $\"2m-7+=+0\"$ or $\"2m-7+=+0\"$
\n" ); document.write( "If $\"2m-7+=+0\"$ then $\"2m+=+7\"$ and so $\"m+=+7%2F2\"$
\n" ); document.write( "So the solution is a double root: $\"m+=+7%2F2\"$ or $\"m+=+3.5\"$
\n" ); document.write( " $\"graph%28400%2C400%2C-3%2C10%2C-5%2C50%2C4x%5E2-28x%2B49%29\"$
