find the vertex and x-intercepts of the parabola described by the equation:
\n" ); document.write( "y=(x+12)(x-2)
\n" ); document.write( "-------------
\n" ); document.write( "If you let y=0 you find the x-intercepts at x=-12 and x=2.
\n" ); document.write( "The x-value of the vertex is half way between -12 and 2 or
\n" ); document.write( "at -5,
\n" ); document.write( "The y-value is f(-5)=(-5+12)(-5-2) = 7*-7 = -49
\n" ); document.write( "Vertex at (-5,-49)
\n" ); document.write( "\"graph%28400%2C300%2C-15%2C10%2C-55%2C10%2C%28x%2B12%29%28x-2%29%29\"
