$\"49x%5E2%2B9=42x\"$
\n" ); document.write( "First, equate to zero and write it out in ax^2+bx+c form:
\n" ); document.write( " $\"49x%5E2-42x%2B9=0\"$
\n" ); document.write( "Apply the quadratic formula:
\n" ); document.write( " $\"x=42%2B-sqrt%28%2842%5E2%29-%284%29%2849%29%289%29%29%2F%282%2A49%29\"$
\n" ); document.write( "Simplify and you can see the discriminant is zero. This means you only have one root to the equation, and leaves you with:
\n" ); document.write( " $\"x=42%2F98\"$
\n" ); document.write( "You can reduce this:
\n" ); document.write( " $\"highlight%28x=3%2F7%29\"$
