Question

Solve for all real values of x.
x, squared, plus, 4, equals, 0
x
2
+4=
0


Solve the problem just like the example below
⬇️
Solve for all real values of x

x² - 16 = 0
+16. +16

x²=16

√x² = ± √16

x= ± 4

Solutions: x=4, x=-4

Answer 1

Solve for all real values of x

x² + 4 = 0
-4. -4

x² = -4

√x² = ± √(-4)

x = ± 2i

Solutions: x = 2i, x = -2i

Since the solutions are imaginary, there are no real solutions for this equation.
