Ethan Adkins

Easy ones like this we just say #x^2=16/9# so #x= \pm \sqrt{16/9} = \pm 4/3#, two solutions.

To solve the equation 9x^2 = 16, first divide both sides by 9 to isolate x^2. Then, take the square root of both sides to solve for x. Remember to consider both the positive and negative square roots. The solution is x = ±(4/3).
