Question

Solve: 2 (Radical x) + 8 = -2

Answer 1

I assume the (Radical x) is \[\sqrt{x}\]
?

Answer 2

\[2 \sqrt{x} = -10\]

Squaring both the sides,

\[4x = 100\]

Divide by 4 both the sides and tell me what you got..

Answer 3

don't you have to divide by 2 first before you square both sides?

Answer 4

You can do that also..

Answer will remain the same..

According to you:

Divide by 2 both the sides:

\[\large \sqrt{x} = -5\]

Squaring both the sides:

\[\large \color{green}{x = 25}\]

Answer 5

That was what my answer was, and I got it wrong on my test ):

Answer 6

And According to me:

\[\large 4x = 100\]

Divide by 4 both the sides:

\[\large x = \frac{\cancel{100}^{25}}{\cancel{4}} = 25\]
