Question \( 14 \) (5 points) What's the standard equation of the circle with the general equation \( x ^ { 2 } + y ^ { 2 } + 4 x - \) \( 2 y - 20 = 0 ? \) 

1) \( ( x - 2 ) ^ { 2 } + ( y + 1 ) ^ { 2 } = 25 \) 

2) \( ( x + 1 ) ^ { 2 } + ( y - 2 ) ^ { 2 } = 5 \) 

3) \( ( x + 2 ) ^ { 2 } + ( y - 1 ) ^ { 2 } = 25 \) 

4) \( ( x + 2 ) ^ { 2 } + ( y - 1 ) ^ { 2 } = 5\) 

Answer

3)(x+2)^2+(y-1)^2=25
