The equation of a cricle is
h being the x coordinate of the given point and k being the y coordinate of the given point (r also being the radius).
Now we have to plug the points into the equation
now just simplify the the equation
Multiply 4 on both sides.
x = 8 / 5
x = 1 3/5
Hope this helps!
X2 + 2x + 10 =0
Can also be written as 2x +2x + 10 =0
4x + 10 =0
4x = -10
x= -10/4
x= -5/2
Answer:
10
