Question

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

Answer 1

x = 0

Explanation:

to solve for x in Solve (x + 1)2 - 4(x + 1) + 2 = 0 using substitution

first open the brackets and then combine the like terms and evaluate.

so,

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

2x + 2 -4x -4 +2 = 0

-2x +0 = 0

-2x =0-0

-2x =0

divide both sides by -2

-2x/-2 = 0/-2

x = 0

therefore the value of x in the expression (x + 1)2 - 4(x + 1) + 2 = 0 using substitution is 0
