Question

What is the solution of the equation? -10 + sqrt x+8 = -4

Answer 1

first, subtract 8 and add 10 from both sides

Answer 2

that will get you sqrt x = -2. then you square both sides

Answer 3

and that gets you x = 4.

Answer 4

but now you have to check it

Answer 5

and when you do, you will see that 4 is wrong.

Answer 6

these are the choices, x=4 isnt one A. 28

B. -2

C. 36

D. 44

Answer 7

because 4 is wrong that means there is no solution. are you sure you typed the problem correctly?

Answer 8

or is it sqrt(x+8)

Answer 9

yeah\[-10+\sqrt{x+8}=-4\]

Answer 10

i thought you meant sqrt of only x not x+8.
\[-10 +\sqrt{x+8}=4\]
\[-10 +x+8 = 16\]
\[x = 16+10-8\]
\[x = 28\]
