To solve the equation by factoring using the difference of squares pattern, we first need to rewrite the equation in the form of (a² - b²) = 0.
Given: 3x² - 20 = 7
Rearranging the equation, we have: 3x² = 27
Dividing both sides by 3, we get: x² = 9
Taking the square root on both sides, we have: x = ±3
Therefore, the correct solutions are x = 3 and x = -3.
