Do I leave my answer in fraction form or in whole number form? How do I know?
\n" ); document.write( "x^2-3x-28=0
\n" ); document.write( "-3+-sqrt((3)^2-4(1)(-28))/(2(1))
\n" ); document.write( "-3+-sqrt(9+112)/(2)
\n" ); document.write( "-3+-sqrt(121)/(2)
\n" ); document.write( "x=(4)/(1) and x=-(7)/(1)
\n" ); document.write( "--------------------------------
\n" ); document.write( "Should be:
\n" ); document.write( "x = [-b +- sqrt(b^2-4ac)]/(2a)
\n" ); document.write( "---
\n" ); document.write( "x = [3 +- sqrt(9-4*1*-28)]/(2
\n" ); document.write( "---
\n" ); document.write( "x = [3 +- sqrt(121)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [3+-11]/2
\n" ); document.write( "----
\n" ); document.write( "x = -8/2 or x = 14/2
\n" ); document.write( "---
\n" ); document.write( "x = -4 or x = 7
