A.-2 and 2
B.-4 and 4
C.-2 and 8
D.-8 and 8

Answer 1

Answer:

i think the answer is option b

Answer 2

Answer:

If x^2 + 16 = 0, then what is x?

Clearer skin, even as an adult.

Here in this problem ,

Where x^2 + 16 = 0

x^2 = 0 - 16

So,

x^2 = -16

Therefore, x = under root -16

x = - (4)^2

so, There won't be any value of x for which given the equation will satisfy.

Hence, No solution.

But if your question will be x^2 - 16 = 0

Then answer will be

x^2 = 16

x = under root of 16

So,

x = +4 and -4
