Answer:
x = 2/3, -2/3
Explanation:
To solve the quadratic equation 9x² = 4, we can use the following steps:
Move the constant term to the right-hand side of the equation:
9x² = 4 => 9x² - 4 = 0
Factor the quadratic expression on the left-hand side of the equation:
9x² - 4 = (3x - 2)(3x + 2)
Set each factor equal to zero and solve for x:
3x - 2 = 0 => x = 2/3
3x + 2 = 0 => x = -2/3
