y = -3x^2 - 10
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=-3, b=-10, and c=0
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, plug this:
\n" ); document.write( "-3 -10 0
\n" ); document.write( "into this: https://sooeet.com/math/quadratic-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "the quadratic vertex is a maximum at: ( -1.67, 8.33 )
\n" ); document.write( "---
\n" ); document.write( "the vertex form of the equation:
\n" ); document.write( "y = a(x - h)^2 + k
\n" ); document.write( "y = a(x + 1.67)^2 + 8.33
\n" ); document.write( "---
\n" ); document.write( "the axis of symmetry is: x = -1.67
\n" ); document.write( "---
\n" ); document.write( "the parabola opens downward (as suggested by a < 0)
