Question

(x-1)^2-2(x+1)+1 плиз ребята

Answer 1

X^2-2x+1-2x-2+1=x^2-4x=x*(x-4).

Answer 2

Sure, let's simplify the expression (x-1)^2 - 2(x+1) + 1:

Step 1: Expand the squared term (x-1)^2 (x-1)^2 = (x-1)(x-1) = x^2 - 2x + 1

Step 2: Distribute the -2 into (x+1) -2(x+1) = -2x - 2

Now, the expression becomes: (x^2 - 2x + 1) - (2x + 2) + 1

Step 3: Combine like terms: x^2 - 2x - 2x + 1 - 2 + 1

Step 4: Simplify: x^2 - 4x + 1 - 2 + 1

Step 5: Combine constants: x^2 - 4x + 2

So, the simplified expression is: x^2 - 4x + 2
