You can put this solution on YOUR website!
h = -16t^2 + 112t
\n" ); document.write( "---
\n" ); document.write( "the t-intercepts of this eqn are its quadratic roots:
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=-16, b=112, and c=0
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation using the quadratic formula, plug this:
\n" ); document.write( "-16 112 0
\n" ); document.write( "into this: https://sooeet.com/math/quadratic-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "the roots of the quadratic are:
\n" ); document.write( "t = 0
\n" ); document.write( "t = 7
\n" ); document.write( "---
\n" ); document.write( "the quadratic vertex is a maximum at: ( t= 3.5, h(t)= 196 )
