NEED ANSWER QUICK!!

In solving the quadratic equation x² +2x-5=0 by completing the square, the following steps are given. To continue solving by completing the square, what should be Step 3?

Answer 1

For Step 3, we need to add 1 to both sides of the equation to isolate the squared term:

A. (x + 1)² = 6

We can now take the square root of both sides to solve for x:

x + 1 = ±√6

Subtracting 1 from both sides, we get:

x = -1 ±√6
