Question

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

Answer 1

Answer:

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

Step-by-step explanation:

To solve the problem shown, you can apply the proccedure shown below:

- Divide both sides of the equation by 9, as following:

$\frac{9x^{2}}{9}=\frac{4}{9}\\\\x^{2}=\frac{4}{9}$

- Apply square root to  both sides of the equation, then you obtain the solution shown below:

$\sqrt{x^2}=\sqrt{\frac{4}{9}}\\\\x=\frac{2}{3}\\x=-\frac{2}{3}$

Answer 2

Answer:

x = 2/3   and x = -2/3

Step-by-step explanation:

We have given equation:

9x² = 4

We have to find the solution of this equation.

multiplying 1/9 to both sides we get,

x² = 4/9

Taking square root on both sides we get,

x =  √4/9

x = ±2/3  is the values of x.
