You can put this solution on YOUR website!
(4-i)^2+2(3-2i)-4\r
\n" ); document.write( "\n" ); document.write( "1st solve (4-i)^2 with the identity (a-b)^2= a^2 + b^2 - 2ab...and we get \r
\n" ); document.write( "\n" ); document.write( " [(4)^2 + (i)^2 - 2(4)(i)] + 2(3-2i)-4 \r
\n" ); document.write( "\n" ); document.write( "[16 + i^2 - 8i ] + 2(3-2i)-4\r
\n" ); document.write( "\n" ); document.write( "Now,lets solve the other part i.e..2(3-2i)-4....here is the simple multipication requried...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "[16 + i^2 - 8i ] + 6 - 4i -4\r
\n" ); document.write( "\n" ); document.write( "or, 16 + i^2 - 8i + 6 - 4i -4\r
\n" ); document.write( "\n" ); document.write( "Now, put together the like variables ....we get..\r
\n" ); document.write( "\n" ); document.write( "i^2 - 8i-4i +16+6-4\r
\n" ); document.write( "\n" ); document.write( "i^2 -12i +22-4\r
\n" ); document.write( "\n" ); document.write( "i^2 -12i +18.......ANSWER\r
\n" ); document.write( "\n" ); document.write( "if further factorization is requried,,,,I suggest that you must 1st check the equation and then let me know...\r
