[tex](x + 6)(2x + 7) \\ = (x \times 2x) + (6 \times 2x) + (x \times 7) + (6 \times 7) \\ = 2 {x}^{2} + 12x + 7x + 42 \\ = 2 {x}^{2} + 19x + 42[/tex]
[tex]2. \: \: (6x - 5)(7x - 4) \\ = (6x \times 7x) + ( (- 5) \times 7x) + (6x \times - 4) + ( (- 5) - 4) \\ = 42 {x}^{2} - 35x - 24x + ( - 9) \\ = 42 {x}^{2} - 11x - 9[/tex]
