Question

Solve the following equation.

Answer 1

the answer a 100% sure

Answer 2

\[9 + \sqrt{x -1}= 1\]
\[\sqrt{x-1}=-8\]

There is no real solution...

Answer 3

is A

Answer 4

The square root of any number - 1 will never result in a negative number.

Answer 5

x=65

Answer 6

yikes

Answer 7

@sebastians pay attention to Malaria
he/she has it

Answer 8

lol @satellite73

Answer 9

If we say that x=65, and resubstitute into the equation:

\[9 +\sqrt{65 - 1} = 1\]
\[\sqrt{64} = -8\]

This is a false statement.

Answer 10

never assume

Answer 11

\[\sqrt{64} = \pm 8\]

Answer 12

So the square root of 64 can be -8?

Answer 13

yep (-8)^2 = 64

Answer 14

wait, what? HAHA i'm so confused

Answer 15

\[9 + \sqrt{x-1} = 1\]
\[\sqrt{x-1} = 1 - 9\]
\[\sqrt{x-1} = -8\]
what malaria did wrong ehre is i think he took the square root...he should have squared
\[(\sqrt{x-1})^2 = (-8)^2\]
\[x - 1 = 64\]
yada yada

Answer 16

OH! so it is 65?

Answer 17

if 64 + 1 = 65
