Question

Solve x2 = −49 by using square roots.

A. The solution is 7.
B. There are no real solutions.
C. The solution is −7.
D. The solutions are 7 and −7.

Answer 1

Answer is B, There are no real solutions

X=7i, -7i

Answer 2

Option B, There are no real solutions

Explanation:

Step 1: Square root both sides

`x^2 = -49`

`√(x^2) = √(-49)`

Since we are trying to square root a negative it would cause imaginary solutions so in conclusion we have no real solutions.

Answer: Option B, There are no real solutions
