1. Find the equation.
2. Get two points.
3. Take the derivative of the parabola.
4. Use slope formula and set the slope of each tangent line to the point.
5.Equal the slope to (x,x^2)
6. Solve for x
8.Take the x-coordinates of tangency and plug each of the coordinates into y=x^2
9. Find the y-coordinates.
The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
Answer:
the second one is correct
