dik: f(x) = 2x^2 -9x-5 g(x)=2x+1 h(x)=akar x+2 tentukan, (f+g) (x), (f/g) (x), dan (f.h) (x) mohon bantuannya

[tex]\huge f(x)=2x^2-9x-5[/tex]
[tex]\huge g(x)=2x+1[/tex]
[tex]\huge h(x)=\sqrt{x}+2[/tex]

[tex]\huge (f+g)(x)=2x^2-7x-4[/tex]
[tex]\huge (\frac{f}{g})(x)=(x+5)(2x+1)-\frac{10}{2x+1}[/tex]
[tex]\huge (f\cdot h)(x)=(x^\frac{1}{2}+2)(2x^2-9x-5)[/tex]

Maaf jika ada salah hitung.
