Question

Solve x2 = −169.

Undefined
13
±13
−13

Answer 1

no solution because squareing a number makes it positive (except for 0, squaring it results in 0)

the answer is undefined
(if you know complex number then the answer is x=13i)

Answer 2

Option A is correct

Undefined

Explanation:

Given that:

`x^2=-169`

Taking square root both sides we have;

`√(x^2)=√(-169)`

⇒
`x = \pm √(-169)`

There are no real solution but rather than there are two complex number i,e 13i, -13 i

Therefore, the value of x are undefined.
