I need the general form of (x-6)²+(y-1)²=81​

Sagot :

Answer:

x² + y² - 12x - 2y - 44 = 0

Step-by-step explanation:

( x - 6 )²+( y - 1 )² = 81

( x - 6 )( x - 6 ) + ( y - 1 )( y - 1 ) = 81

(x² - 6x - 6x + 36 ) + ( y² - y - y + 1 ) = 81

(x² - 12x + 36 ) + ( y² - 2y + 1 ) = 81

x² + y² - 12x - 2y + 36 + 1 = 81

x² + y² - 12x - 2y + 36 + 1 - 81 = 0

x² + y² - 12x - 2y - 44 = 0
