Two lines and a point are guaranteed to be coplanar if the two lines share only a single point.
Hope this helped :)
Answer:
I would suggest using a app called desmos if you put in the table it will make the graph for you :)
For roots r1 and r2, the factors are (x-r1)(x-r2)
given
r1 and r2 arer 5+i√2 and 5-i√2
(x-(5+i√2))(x-(5-i√2))=
(x-5-i√2)(x-5+i√2)=
remember that i²=-1
x²-10x+27
