Algebra.Com's Answer #43592 by uma(370)![]() ![]() ![]() You can put this solution on YOUR website! The equation of the circle with centre C(3,-2) and radius 4 is given by:\r \n" ); document.write( "\n" ); document.write( "(x-3)^2 + (y-(-2))^2 = 4^2\r \n" ); document.write( "\n" ); document.write( "==> (x-3)^2 + (y+2)^2 = 16\r \n" ); document.write( "\n" ); document.write( "On expanding we get,\r \n" ); document.write( "\n" ); document.write( "x^2 - 6x + 9 + y^2 + 4y + 4 = 16\r \n" ); document.write( "\n" ); document.write( "==> x^2 + y^2 - 6x + 4y + 13 = 16\r \n" ); document.write( "\n" ); document.write( "==> x^2 + y^2 - 6x + 4y + 13 - 16 = 0 [adding - 16 to both the sides]\r \n" ); document.write( "\n" ); document.write( "==> x^2 + y^2 - 6x + 4y - 3 = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Good Luck!!! \n" ); document.write( " |
