Question

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

Answer 1

Answer:

x = ± $\frac{2}{3}$

Step-by-step explanation:

9x² = 4 ( divide both sides by 9 )

x² = $\frac{4}{9}$ ( take square root of both sides )

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

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

Answer 2

Answer:

x= 2/3, -2/3

Step-by-step explanation:

9x² = 4

To solve this quadratic, divide each side by 9

x^2 = 4/9

Take the square root of each side

sqrt(x^2) = sqrt(4/9)

x = ±2/3
