Question 1056948
Follow the process of completing the square to solve x^2 - 10x + 8 = 0.

How will the left side of the equation factor in step 5?

(x - 10)^2
(x - 20)^2
(2x - 10)^2

I had answered (x-10)^2 and was wrong.

<pre>
x^2 - 10x + 8 = 0.

x^2 - 10x + 25 - 25 + 8 = 0.

(x^2 - 10x + 25) - 25 + 8 = 0.

{{{(x-5)^2 -17}}} = 0,

{{{(x-5)^2}}} = 17,

x - 5 = +/- {{{sqrt(17)}}},

x = {{{5 +- sqrt(17)}}}.
