Question

What are the solution(s) to the quadratic equation 9x2 = 4?

Answer 1

we have

$9x^{2}=4$

Divide both sides by $9$

$9x^{2}/9=4/9$

$x^{2}=4/9$

Square root both sides

$x=(+/-)\sqrt{\frac{4}{9}}$

$x=(+/-)\frac{2}{3}$

so

the solutions are

$x1=\frac{2}{3}$

$x2=-\frac{2}{3}$

therefore

the answer is the option

x = 2/3 and x = -2/3

Answer 2

The answer would be x= 2/3 and x= -2/3
