Answer:
B
Step-by-step explanation:
x^2 + 1 = 0
subtract both sides by one.
x^2 + 1 - 1 = 0 - 1
x^2 = -1
put both sides under square root to find the value of x
sqrt (x^2) = sqrt(-1)
we know that a number inside a square root must always be greater or equal to 0. thus, we don't have a real solution.
✨Extra - It says "no REAL solution" because imaginary solutions exist which are the set of complex numbers in an imaginary coordinate system.
Answer:
B
Step-by-step explanation:
x² + 1 = 0 ( subtract 1 from both sides )
x² = - 1
no real number when squared gives a negative value.
Thus the equation has no real solution
