9m²+16=24m
\n" ); document.write( "add -24m to both sides
\n" ); document.write( "9m^2-24m+16=24m-24m
\n" ); document.write( "9m^2-24m+16=0
\n" ); document.write( "x1= (-(-24)+sqrt((-24)^2-4*9*16))) /(2*9)
\n" ); document.write( "x1= 1.333\r
\n" ); document.write( "\n" ); document.write( "b^2-4ac =(-24)^2-4*9*16)=0
\n" ); document.write( "There is only 1 root\r
\n" ); document.write( "\n" ); document.write( "-3x²+7x=0
\n" ); document.write( "-x(3x-7)=0
\n" ); document.write( "x=0
\n" ); document.write( "or
\n" ); document.write( "3x-7=0
\n" ); document.write( "x=7/3
