Focus E: Specialized Factoring Techniques

1. x⁴ - 7x² + 10 = (x² - 5)(x² - 2)

2. 2x⁴ + 5x² - 3 = (2x² - 1)(x² + 3)

3. 2x⁴ + 12x² + 18 = 2(x⁴ + 6x² + 9)    Remove a common factor first 
                                                               
                               = 2(x² + 3)(x² + 3)
