Solve. x2 + 6x = 10

-3 ± sqrt 10

-3 ± sqrt 7

-3 ± sqrt 19

-3 ± sqrt 13

... ?

We can solve the given equation above by doing the completing the square method. We do as follows:

x^2 + 6x = 10

x^2 + 6x + 9 = 10 + 9

(x+3) ^2 = 19

√ (x+3) ^2 = √19

x + 3 = √19

Therefore, the correct answer from the choices listed above is the third option, - 3 ± sqrt 19. Hope this answers the question. Have a nice day.
