What is the x-intercept of the graph of y = x^2 – 4x + 4 ?

Given the equation of the curve y= x^2 - 4x +
4

We need to find the x-intercept
.

We know that the c-intercept is the point where the curve
y meets the x-axis.

When the curve touches the x-axis, the
values of y will be 0.

==> y= x^2 - 4x + 4 =
0

Now we will
factor.

==> (x-2)(x-2) =
0

==> x =
2

Then, the x-intercept is the point ( 2,
0).
