Question

Solve the equation.
9x^2 - 4 = 0

Answer 1

9x^2=4
x^2=4/9
x=+-sqr4/9=+-2/3

Answer 2

9x^2=4
x=+-2/3

Answer 3

9x^2=4
9x=sqrt4
9x=4
x=4/9
x=2/3

Answer 4

if u sqr both parts of the eq u'd have
3x=+-2
x=+-2/3

Answer 5

=(3x+2)*(3x-2)
x=+or-2/3

Answer 6

\[9x^2 - 4 = 0 \rightarrow9x^2=4 \rightarrow x^2=\frac{4}{9} \rightarrow x=\sqrt{\frac{4}{9}}\]
