Question

In solving \\(x^{2}=3\\) we obtain _______

options

\\(â€" 1, 1 \\)

\\(1, - 4\\)

\\(1, - 1\\)

\\(â€" 1, 4 \\)

Answer 1

For this case we must solve the following equation:

`x ^ 2 = 3`

So we have to:

Applying square root to both sides of the equation:

`x = \pm \sqrt {3}`

Thus, we have two roots:

`x_ {1} = \sqrt {3} = 1.7321\\x_ {2} = - \sqrt {3} -1.7321`

Answer:

`x_ {1} = 1.7321\\x_ {2} = - 1.7321`
