(x + 7)^2 – 11 = 0<br> lesser =<br> greater =

Andreyy89

Answer:

Lesser = - $\sqrt{11}$ - 7 = -10.317

Greater = + $\sqrt{11}$ - 7 = -3.683

Step-by-step explanation:

I am assuming you are asking for the lesser x solution and greater x solution.

(x + 7)^2 – 11 = 0

(x + 7)^2 = 11

x+7 = ± $\sqrt{11}$

x = ± $\sqrt{11}$ - 7

Lesser = - $\sqrt{11}$ - 7 = -10.317

Greater = + $\sqrt{11}$ - 7 = -3.683
