The general form of the equation of a circle is x2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is A)
jolli1 [7]
The common way of transforming the general form to the standard form is by using the completing the square method. But there is also a neat shortcut to knowing the h, k and r values right away.
The general formula is: 
x²+y²+Dx+Ey+F = 0
x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

Solving for h:
-2h = 42
h = -21

Solving for k:
-2k = 38
k = -19

Solving for r:
-47 = (-21)² + (-19)² - r²
r = √849

Standard form of given circle is:
(x+21)² + (y+19)² = 849

Answers:
1) B
2) B
3) B
4) D
