Answer: [tex]x^2+\frac{11}{4}x+\frac{3}{2}[/tex]
Step-by-step explanation:
Use FOIL:
[tex]x^2+\frac{3}{4} x+\frac{4}{2} x+\frac{12}{8}[/tex]
[tex]x^2+\frac{3}{4} x+\frac{8}{4}x+\frac{12}{8} \\[/tex] Make 3/4x and 4/2x have the same denominator
[tex]x^2+\frac{11}{4}x+\frac{12}{8}[/tex] Add like terms
[tex]x^2+\frac{11}{4}x+\frac{3}{2}[/tex] Simplify
