Answer:
x= [tex]\sqrt{\frac{4}{9}[/tex]
Step-by-step explanation:
[tex]9x^{2} -4=0[/tex]
add 4 on both sides to cancel it out
[tex]9x^{2} =4[/tex]
divide by 9 on both sides to isolate x
[tex]x^{2} =\frac{4}{9}[/tex]
to get rid of the squared you use square root on both sides
[tex]x=\sqrt\frac{4}{9}[/tex]
