1. (2x - 5)(2x + 5)

Solution

[tex](2x - 5)(2x + 5) \\ = 4 {x}^{2} + 10x - 10x - 25 \\ = 4 {x}^{2} - 25[/tex]

2. (3x + 2)(3x - 2)

Solution

[tex](3x + 2)(3x - 2) \\ = 9 {x}^{2} - 6x + 6x - 4 \\ = 9 {x}^{2} - 4[/tex]

3. (3x - 1)(3x + 1)

Solution

[tex](3x - 1)(3x + 1) \\ = 9 {x}^{2} + 3x - 3x - 1 \\ = 9 {x}^{2} - 1[/tex]

4. (2x + 3)(2x - 3)

Solution

[tex](2x + 3)(2x - 3) \\ = 4 {x}^{2} - 6x + 6x - 9 \\ = 4 {x}^{2} - 9[/tex]
