Doprowadz do rownania okręgu (x-a)² + (y-b)² = r² a) (x-2)² + y² = 2 b) x² + y² + 6x - 2y + 6 = 0 c) x² + (y + 3)² = 2 d) x² + y² + 2x - 8y + 13 = 0 (ze wszystkimi obliczeniami)

a) (x-2)² + y² = 2 (x-2)² + ( y-0)² =( √2)² b) x² + y² + 6x - 2y + 6 = 0 (x²+6x+9)-9+(y²-2y+1)-1+6=0 (x+3)²+(y-1)²= 4 (x+3)²+(y-1)²= 2² c) x² + (y + 3)² = 2 (x-0)² + (y + 3)² = (√2)² d) x² + y² + 2x - 8y + 13 = 0 (x²+2x+1)-1+(y²-8y+16)-16 +13=0 (x+1)²+(y-4)²=4 (x+1)²+(y-4)²=2²
