Given the solutions (zeroes) are -5 and 2. That means the quadratic equation is:
\n" ); document.write( "a(x+5)(x-2) = 0
\n" ); document.write( ".
\n" ); document.write( "We cannot say what the value of 'a' is unless we have some additional information.
\n" ); document.write( "'a' is simply a constant that would affect the graph's position.
\n" ); document.write( ".
\n" ); document.write( "(x+5)(x-2) = x^2 +3x -10
\n" ); document.write( ".
\n" ); document.write( "In the following graph:
\n" ); document.write( "The red line assumes 'a' = 1.
\n" ); document.write( "The green line assumes 'a' = -1.
\n" ); document.write( "The blue line assumes 'a' = 1/2.
\n" ); document.write( "The purple line assumes 'a' = -1/4.
\n" ); document.write( ".
\n" ); document.write( "

\n" ); document.write( "

\n" );
