Answer:

x = ± [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

9x² - 4 = 0 ( add 4 to both sides )

9x² = 4 ( divide both sides by 9 )

x² = [tex]\frac{4}{9}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{4}{9} }[/tex] = ± [tex]\frac{\sqrt{4} }{\sqrt{9} }[/tex] = ± [tex]\frac{2}{3}[/tex]
