please solve this equation 64k^2+112k+49=0, thank you
\n" ); document.write( "Plug into the quadratic formula $\"x=%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\"$
\n" ); document.write( " $\"k=-112+%2B-+sqrt%28+112%5E2-4%2A64%2A49%29%2F%282%2A64%29\"$
\n" ); document.write( " $\"k=-112+%2B-+sqrt%28+12544-12544%29%2F%28128%29\"$
\n" ); document.write( " $\"k=-112+%2B-+sqrt%280%29%2F%28128%29\"$
\n" ); document.write( "Simplify -112/128 by dividing the numerator -112 and denominator 128 by 16
\n" ); document.write( " $\"k=%28-7+%2B-+sqrt%280%29%2F%288\"$
\n" ); document.write( "Since the discriminant is zero. The equation will have 2 equal roots. Where only one root shows.
\n" ); document.write( " $\"k=%28-7+%2B-+sqrt%280%29%2F%288\"$
\n" ); document.write( "k=-.875 Math Fract =-7/8
\n" ); document.write( "k=-7/8 k=-7/8\r
