Answer:
Explanation:
To factor the equation u^2 - 4u + 4, we need to find two numbers that add up to -4 and multiply to 4.
The two numbers are -2 and -2 because:
-2 + (-2) = -4 and (-2)(-2) = 4
Using these numbers, we can factor the equation as:
u^2 - 4u + 4 = (u - 2)(u - 2) = (u - 2)^2
Therefore, the factored form of the equation is (u - 2)^2.
