Which of the following are solutions to the equation below? check all that apply. 4x2 - 81 = 0

Hi there!

Let's solve this equation step by step!

First add 81 to both sides.

Divide both sides by 4.

Take the square root of both sides (and the negative root of 20 1 / 4)

Therefore the two solutions are
x = 4.5 and x = - 4.5
