What was the error He did not square 36 correctly since 3626 Or He did not solve the equation completely since there is a positive answer as well class=

Respuesta :

When we have a power:

[tex] {g}^{2} = 36[/tex]

We should use a root to solve:

[tex]g = \sqrt{36} [/tex]

When we have a square root, there are two solutions: positive and negative.

[tex]\boxed {g = + 6 \: \textsf { or} \: - 6}[/tex]

So, the correct answer is:

"He did not solve the equation completely since there is a positive answer as well."
