Solve (x + 1)2 - 4(x + 1) + 2 = 0 using substitution. U=

х

4(x +1)

O x +1

(x + 1)2

Step-by-step explanation:

We are given the equation . Consider the substitution u = (x+1). Then the equation turns out to be

Recall that given a second degree polynomial of the form then its solutions are given by the expression

In our case, a = 1, b = -4 and c =2. Then the solutions are

We have that x = u-1. So the original solutions are

step-by-step explanation:

my butt

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
