We have that
Let y be the first root, then y - 6 will be the second one. Since both roots make the quadratic equation equal to 0, we have that:
Solve for y:
Plug in y = 5/2 into original quadratic equation and solve for c:
So, the answer is c = -35/4

Answer:
radius = 8
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 64 ← is in this form
with r = = 8
