The discriminant is -439 and so there are no real solutions.
It has no real roots.
It works out that the centre of the circle is at (-0.5, 1.5) and its diameter is the square root of 28
For x = -4 2x2 + x = 2 (-4)2 + (-4) = 32 - 4 = 28
22+22+28+28=100.

it equals 28
it is 28
3x + 7 = -4x + 28 implies 7x + 7 = 28
59
That equals 28
25 + 28 + 29 = 82
