Bruno needs to solve the equation x2 + 6x – 8 = 0 by completing the square. which pair of steps is the most efficient way to begin?

There are probably some choices we're not being shown, but let's just do the whole procedure.

x² + 6x - 8 = 0

Step one: move the 8 to the other side.

x² + 6x = 8

Step two: add (6/2)²=9 to both sides.

x² + 6x + 3² = 8 + 9

Step three: Factor

(x + 3)² = 17

Step four: take the square root

x + 3 = ±√17

Step five: Solve for x,

x = -3  ± √17

i found two solutions,   n = 2 • ± √3 = ± 3.4641
