Write the equation x² + 6x + y² – 8y = 19 in standard form.

kirza4 [7]

Answer:

Formula used :

<u>x²+2xy+y²</u><u> </u><u>=</u><u> </u><u>(x+y)²</u>
<u>x²-2xy+y²</u><u> </u><u>=</u><u> </u><u>(x-y)²</u>

$→{x}^{2} + 6x + {y}^{2} - 8y = 19 \\ ({x}^{2} + 2.3.x + {3}^{2} ) +({y}^{2} - 2.4.y + {4}^{2} ) = 19 + {3}^{2} + {4}^{2} \\ {(x + 3)}^{2} + {(y - 4)}^{2} = 19 + 9 + 16 \\ \boxed{ {(x + 3)}^{2} + {(y - 4)}^{2} = 44}✓$

<u>3) (x+3)²+(y-4)²=44</u> is the right answer.
