to find the x intercepts put y=0 and for the first equation you will get (3+sqrt(13))/2 and (3-sqrt13)/2. sum these two and you will get x intercept =3units.

similarly in the second one you will get x intercept=2 units (using the properties of qudratic roots)

To find the x-intercept, make y=o in each equation

In the second equation, if y=o, then

x^2-2x+4=0

Solve this quadratic equation

x=2

So the x-intercept has the following coordinates: (2, 0)
