Select all the functions that have no real number solution.
4x^2 + 100 = 0
3x^2-9= 0
x²+1=0

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.

b is the answer that makes most sense
