Answer:
we have the centre as:
(−2,0)
radius √12=2√3
Explanation:
The standard equation of a circle is
(x−a)2+(y−b)2=r2
where (a,b)
is the centre, and
r is the radius,
we thus have to complete the square on the given equation.
x2+y2+4x−8=0
rearrange slightly
x2+4+y2−8=0(x2+4+2)+y2−8−22=0(x+2)2+y2−12=0(x+2)2+y2=12
comparing with
(x−a)2+(y−b)2=r2
we have the centre as:
(−2,0)
radius
√12=2√3

Answer:
Step-by-step explanation:
g(m) = 0
2-4m=0
2=4m
2/4=m
1/2=m------(1
p(1/2)= -3(1/2) - { 2(1/2) + (5- 1/2) } +7
= -3/2 - { 1 + 9/2} +7
= -3/2 - ( 11/2) +7
=-14/2 +7
= -14 + 14 /2
= 0/2
= 0...
since p(m)= 0,
we can say that g(m) is a factor of p(m)
hence, it has been simplified correctly...
