00:01 Hi, in this question, given equation is minus x squared minus y squared plus azure divided by 4 plus 8x minus 10y equals 45.
00:13 On rearranging this equation, we get minus x squared plus 8x minus y squared minus y squared minus 10y plus z squared by 4 equals 45.
00:29 Again it can be written as on taking minus commonly outside and go to right hand side, then we get x squared minus 8x plus y squared plus 10y minus z squared divided by 4 equals minus 45...
