Answer:
What goes in the blank is 2
Step-by-step explanation:
In this question, we want to know what goes into the bracket when factorizing the expression above.
What we have a problem with is the terms x^2 - 4x + 4
We can rewrite this as;
x^2 -2x - 2x + 4
x(x-2) -2(x - 2)
That would thus be (x-2)^2
What goes into the bracket is thus the number 2
