Answer:
± sqrt(3) i =x
Step-by-step explanation:
x^2 +25 + 2 = 2x^2 + 30
Combine like terms
x^2 + 27 = 2x^2 +30
Subtract x^2 from each side
x^2 + 27 - x^2 = 2x^2 - x^2 +30
27 = x^2 +30
Subtract 30
27-30 = x^2
-3 = x^2
Taking the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) =x
±sqrt(-1) sqrt(3) =x
We know the square root of -1 = i
± sqrt(3)i =x
