x = 0 or x = 2
(0, -14)

x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i
r=0 is the solution...
a = [ 0, 4 ]
x-2y=0 x=2y The solution set is the set of all (x,y) such that x=2y
x = 0 or x = 2
(0, -14)
'x' must be zero, so the solution set is [ 0 ].

Not sure about the set builder notation, but Q = {0}, the set consisting only of the number 0.
Using the quadratic formula, I found the solution set is x=2,x=-9
7 and (-3/2)
x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i
r=0 is the solution...
They are: x = 5/3 and x = -3
