4x^2+x-3=0
\n" ); document.write( "compare with ax^2+bx+c=0
\n" ); document.write( "Find the roots of the equation by quadratic formula
\n" ); document.write( "a= 4 b= 1 c= -3
\n" ); document.write( "
\n" ); document.write( "b^2-4ac= 1 - -48
\n" ); document.write( "b^2-4ac= 49 $\"sqrt%28%0949%09%29\"$ = 7
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( " $\"x1=%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( "x1=( -1 + 7 )/ 8
\n" ); document.write( "x1= 0.75
\n" ); document.write( "x2=( -1 -7 ) / 8
\n" ); document.write( "x2= -1
\n" ); document.write( "The roots are 0.75,-1
