Question

X squared plus 8 squared equals 9 What is X?

Answer 1

Answer:

x = $i\sqrt{55} , -i\sqrt{55}$

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- $\sqrt{-55}$

Simplify

x = $i\sqrt{55} , -i\sqrt{55}$

Hope this helps!
