1) x^2+5x-14 = 0
\n" ); document.write( " x^2+7x-2x-14 =0
\n" ); document.write( " x(x+7)-2(x+7) = 0
\n" ); document.write( " (x+7)(x-2)=0
\n" ); document.write( " x+7=0 or x-2=0
\n" ); document.write( " x= -7 or x=2\r
\n" ); document.write( "\n" ); document.write( "2) 49x^2 - 25=0
\n" ); document.write( " (7x)^2- 5^2 =0
\n" ); document.write( " (7x+5)(7x-5) =0
\n" ); document.write( " 7x+5 =0 or 7x-5=0
