Algebra.Com's Answer #19298 by mukhopadhyay(490)![]() ![]() ![]() You can put this solution on YOUR website! 13x^2-650x-6000=0 \n" ); document.write( "=> 13(x^2-50x) = 6000 \n" ); document.write( "=> 13(x^2-50x+25^2) = 6000 + 13*25^2 \n" ); document.write( "=> 13(x-25)^2 = 6000+8125 \n" ); document.write( "=> 13(x-25)^2 = 14125 \n" ); document.write( "=> (x-25)^2 = 14125/13 = 25*565/13 \n" ); document.write( "=> (x-25) = 5*sqrt(565/13) or x = -5*sqrt(565/13) \n" ); document.write( "=> x = 25 + 5*sqrt(565/13) or x = 25 - 5*sqrt(565/13) \n" ); document.write( " |
