4x^2 + 100 = 0
x²+1=0
Step-by-step explanation:
Let's analyze each function:
1)
We can rewrite it as
Or
The term on the left, , is the square of a number, therefore it cannot be negative: so, this equation has no real solutions.
2)
We can rewrite it as
Or
Which has two real solutions:
3)
This can be rewritten as
The term on the left, , is the square of a value: therefore, it cannot be negative. So, this equation has no real solutions.
