64k^2+112k+49=0\r
\n" ); document.write( "\n" ); document.write( "There are different ways to solve this problem but I like and advise to use method of finding roots uisng formula.\r
\n" ); document.write( "\n" ); document.write( "roots, alpha = [-b + sqrt(b^2 - 4ac)]/2a , beta = [-b - sqrt(b^2 - 4ac)]/2a where a = 64, b = 112 and c = 49\r
\n" ); document.write( "\n" ); document.write( "alpha = [-b + sqrt(b^2 - 4ac)]/2a = [-112 + sqrt(112^2 - 4*64*49)]/2*64 = -7/8
\n" ); document.write( "beta = [-b - sqrt(b^2 - 4ac)]/2a = [-112 - sqrt(112^2 - 4*64*49)]/2*64 = -7/8\r
\n" ); document.write( "\n" ); document.write( "the solution is x = -7/8, -7/8
