shoot, sorry that box and then a was a square root symbol on my word processory but it appears on this as a box and special a? strange..
sqrt ( - 7 x - 2 ) = 0 Square both sides

- 7 x - 2 = 0 Add 2 to both sides

- 7 x - 2 + 2 = 0 + 2

- 7x = 2 Divide both sides with -7

x = - 2 / 7
Sweet, thanks!!! :)
