X2 + y2 + 4x – 2y = -1 The equation of a circle in the xy-plane is shown
above. What is the radius of the circle?
A) 2
B) 3
C) 4
D) 9

maybe i can

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
