The answer is 2 root 10.

hope it helps..

Answer 2

Answer:

x = ±2$\sqrt{10}$.

Step-by-step explanation:

40 - x^2 = 0

Subtract 40 from both sides

-x^2 = -40

Divide both sides by -1

x^2 = 40

Find the square root of both sides

x = ±$\sqrt{40}$

x = ±$\sqrt{2 * 2 * 2 * 5}$

x = ±$\sqrt{2^2 * 2 * 5}$

x = ±2$\sqrt{2 * 5}$

x = ±2$\sqrt{10}$

Hope this helps!
