Solve for x in the equation x squared + 2 x + 1 = 17.
x = negative 1 plus-or-minus startroot 15 endroot
x = negative 1 plus-or-minus startroot 17 endroot
x = negative 2 plus-or-minus 2 startroot 5 endroot
x = negative 1 plus-or-minus startroot 13 endroot

Option B.

Step-by-step explanation:

The given equation is

Subtract both sides by 17.

         .... (1)

If a quadratic equation is , then by quadratic formula

In equation (1), a=1, b=2 and c=-16. Using quadratic formula we get

Taking out common factors.

Therefore, the correct option is B.

The answer to your question is the second option

Step-by-step explanation:

Process

1.- Write the equation

                                 x² + 2x + 1 = 17

Factor the first term

                                 (x + 1)² = 17

Get the square root

                                 (x + 1) =

Result

                                x₁ = - 1 +

                                 x₂ = -1  -
