Given information
We are given the parabolic equation 
and 
.
Step-by-step explanation
Step 1.
The parabola intersect the 
-axis at 
.
intersect the -axis at .Notice that is a quadric formula with negative discriminant, therefore, it has no real solutions.
is a quadric formula with negative discriminant, therefore, it has no real solutions.All points on the parabola has the form 
.
has the form .All points on the parabola has the form 
.
has the form .We know that the slope of a tangent at any point 
is the derivative at that point : 
.
is the derivative at that point : .Applying The Power Rule and The Constant Multiple Rule, we obtain :
Assume that there is a tangent that passes through those two points.
Hence, we required that derivative has common solution :
