\n" ); document.write( "Find the equation of the parabola in the form of y = a(x-p)(x-q), given the points are (-2,21), (-1,0) and (5,0).
\n" ); document.write( "
y = a(x – p)(x – q)
\n" );
document.write( "Substitute - 1 for p, 5 for q, and (- 2, 21) for (x, y) in the above equation.
\n" );
document.write( "This should result in a = 3
\n" );
document.write( "Then substitute 3 for a, - 1 for p, and 5 for q in the above equation.\r
\n" );
document.write( "\n" );
document.write( "Correct equation:  \"highlight_green%28matrix%281%2C3%2C+y%2C+%22=%22%2C+3%28x+%2B+1%29%28x+-+5%29%29%29\"
