Solve using the quadratic formula: 5x^2 − 8x − 3 = 0 \r
\n" ); document.write( "\n" ); document.write( "quadratic formula is\r
\n" ); document.write( "\n" ); document.write( "(-b+or-sqrt(b^2-4ac)/2a)\r
\n" ); document.write( "\n" ); document.write( "(8+or-sqrt(64-4*5*(-3))/2*5
\n" ); document.write( "(8+or-sqrt(64+60)/10
\n" ); document.write( "(8+or-sqrt(124))/10\r
\n" ); document.write( "\n" ); document.write( "x=(8+12)/10=2
\n" ); document.write( "x=(8-12)/10=-4/10=-2/10=-.2\r
