Question

What are the roots of x^2-4x+4?

Answer 1

The root of the equation x^2-4x+4 is x=2.

To find the root you have to replace y with 0 and then solve for x.

Hope I could help! :)

Answer 2

The roots are just the zero value of the formula. To find these, we factor:

(x - 2)(x - 2)

(x - 2)^2

to make this into a zero, we set x-2 = 0, then solve for x

x = 2

If x = 2, then the brackets = 0, and those are the roots

The roots are x = 2
