Question

Part 1. solve (x + 1)2 – 4(x + 1) + 2 = 0 using substitution. u =
a. x b. 4(x +1) c. x +1 d. (x + 1)2
part 2 select the solution(s) of the original equation.

Answer 1

Answer:

x=4

Step-by-step explanation:

(x+1)2-4(x+1)+2 = 0

or 2x+2-4x+4+2-2 = -2

or -2x+6 = -2

or -2x+6-6 = -2-6

or -2x = -8

or 2x = 8 (- and - cancelled)

or 2x/2 = 8/2

or x = 4

Answer 2
