solve
\n" ); document.write( "t^2 + 4t = 1
\n" ); document.write( "t^2 + 4t -1 = 0
\n" ); document.write( "Use the Quadratic Formula:
\n" ); document.write( "t = [-b +- sqrt(b^2-4ac)]/(2a)
\n" ); document.write( "---
\n" ); document.write( "t = [-4 +- sqrt(16-4*1*-1)]/2
\n" ); document.write( "---
\n" ); document.write( "t = [-4 +- sqrt(20)]/2
\n" ); document.write( "---
\n" ); document.write( "t = [4 +- 2sqrt(5)]/2
\n" ); document.write( "---
\n" ); document.write( "t = 2+sqrt(5) or t = 2-sqrt(5)
