Solve x 2 + 9x + 8 = 0 by completing the square. what are the solutions? a.{1,-8} b.{1, 8} c.{-1,-8}

So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x:

Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside:

Now you can rewrite the equation as

Now using zero product property, solve for x:

In short, the solutions are {-1,-8}, or C.
