None of the given options hold true here.\r
\n" ); document.write( "\n" ); document.write( "Let us consider a=b=2; and c=9 in the given equation (x-a)(x-b)=c
\n" ); document.write( "So, (x-2)^2=9=>(x-2)=3 or (x-2)=-3
\n" ); document.write( "=>x=5 or x=-1; same as p=5 and q=-1\r
\n" ); document.write( "\n" ); document.write( "This comes down to 5(value of p) and -1(value of q) are the roots of the equation (x-a)(x-b)=c where a=2, b=2 and c=9; \r
\n" ); document.write( "\n" ); document.write( "Now,
\n" ); document.write( "(x-p)(x-q)+c=0 gives
\n" ); document.write( "(x-5)(x+1)+9=0
\n" ); document.write( "=>x^2-4x-5+9=0
\n" ); document.write( "=>x^2-4x+4=0
\n" ); document.write( "=>(x-2)^2=0
\n" ); document.write( "=>x=2 or x=-2
\n" ); document.write( "The roots of the given equation are 2 and -2\r
\n" ); document.write( "\n" ); document.write( "The roots contradict with all given options in terms of a, b, or c
\n" ); document.write( "
\n" );
