Answer:
5. [tex]6x^2 - x - 2[/tex]
6. [tex]9x^2 - 15x + 6\frac{1}{4}[/tex]
Step-by-step explanation:
5:
- [tex](x+ \frac{1}{2}) (6x-4)[/tex]
- [tex](x)(6x) + (x)(-4) + (\frac{1}{2})(6x)+(\frac{1}{2})(-4)[/tex]
- [tex]6x^2 - 4x + 3x - 2[/tex]
- [tex]6x^2 - x - 2[/tex]
6:
- [tex](3x-\frac{5}{2})^2[/tex]
- [tex](3x - \frac{5}{2})(3x - \frac{5}{2})[/tex]
- [tex](3x)(3x) + (3x)(\frac{-5}{2}) + (\frac{-5}{2})(3x) + (\frac{-5}{2})(\frac{-5}{2})[/tex]
- [tex]9x^2 - \frac{15}{2}x - \frac{15}{2}x + \frac{25}{4}[/tex]
- [tex]9x^2 - 15x + \frac{25}{4}[/tex]
- [tex]9x^2 - 15x + 6\frac{1}{4}[/tex]
