Question

Hi can someone please complete the square step by step. thanks x² + 8x + 1 = 0

Answer 1

Answer:

x = -1/9

Step-by-step explanation:

first let's think of x as 1x so than x^2 is basically 1x.

you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.

than you add x and 8x which equals 9x.

you bring the problem down one more time so 9x + 1 = 0.

you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.

So than you bring the rest of the problem down 9x = -1

Last thing you do is divide 9 from both sides which x = -1/9.
