Question

What is the answer for this in square root form

Answer 1

x = ± sqrt(-49)

or x = ± 7i

Explanation:

x^2 +49 = 0

Subtract 49 from each side

x^2 +49 -49 = 0-49

x^2 = -49

Take the square root of each side

sqrt(x^2) = ± sqrt(-49)

x = ± sqrt(-49)

We have to complex numbers to solve

x = ± sqrt(-1) sqrt(49)

sqrt(-1) = i

x = ±i *7

x = ± 7i
