An equation x^2 -6x +18 = 0
the line y= 41 meets c at the point r.
find the x-coordinates of r, giving you your answer in the form p + q(sqrt( where p and q are integers.
i'm confused about this representation, i got -3 and 9 as the x coordinates yet i have no idea how to place it into this formula. the answer is 3 + 4(sqrt(2)) but i have no idea as to how to arrive at this. do i use completed square form?
