Answer:
x=1/3
Step-by-step explanation:
9x^2-1=0
Add 1 to both sides
9x^2=1
Divide both sides by 9
x^2=1/9
Square root both sides
x=1/3
Answer:
[tex]x=\frac{1}{3}[/tex] or [tex]x = -\frac{1}{3}[/tex]
Step-by-step explanation:
[tex]9x^{2} -1 = 0[/tex]
[tex]9x^{2} = 1[/tex]
[tex]x^{2} = \frac{1}{9}[/tex]
[tex]x = +-\sqrt{ \frac{1}{9}[/tex]
[tex]x=\frac{1}{3}[/tex] or [tex]x = -\frac{1}{3}[/tex]
