Best ResponseYou've already chosen the best response.1x^2 + 8x + 4 = 0 =====> let's take as (8/2)^2 (x + x^2 + 8x + (8/2)^2  (8/2)^2 + 4 = 0 x^2 + 8x + (42)^2  (4)^2 + 4 = 0 x^2 + 8x + 16  16 + 4 = 0 (x + 4)^2  16 + 4 = 0 (x + 4)^2  12 = 0 <===== completing the square (x + 4)^2 = 12 (x + 4) = +/ √(12) x =  4 +/ √(4 * 3) x =  4 +/ 2√(3) the reason i chose completing the square is because we can't use factoring. we can use quadratic formula, but it is longer. we can use graphing but it is more work.
