how it would be solved by graphing, factoring, the quadratic formula, and by completing the square.

3. TAKEBACKMATH Group Title

okay completeing teh square: x2+6x +8=0 x2 +6x = -8 move the 8 over use this formula (b/2)~2 so its (6/2)~2 oe (3)~2 = 9 x2 +6x +9 = -8 +9 add the 9 to both sides (x+3)~2 = 1 $(x+3)^{2} = 1$

then

5. TAKEBACKMATH Group Title

$\sqrt{(x+3)^{2}} = \pm \sqrt{1}$ sqaure root both sides

6. TAKEBACKMATH Group Title

x+3 = + or - 1 -3 -3 subtract 3 from both sides x=+1 -3 and -1-3 or -2, -4

8. TAKEBACKMATH Group Title

x= -2, -4 yes

for completing the sqaure
