Hej!
[tex]u(x) = 17 {x}^{4} - 14 {x}^{2} + 7x - 5 \\ \\ w(x) = 6 {x}^{3} + 11 {x}^{2} - 5x + 5 \\ \\ g(x) =3 (17 {x}^{4} - 14 {x}^{2} + 7x - 5) - (6 {x}^{3} + 11 {x}^{2} - 5x + 5) = \\ \\ = 51 {x}^{4} - 42 {x}^{2} + 21x - 15 - 6 {x}^{3} - 11 {x}^{2} + 5x - 5 = 51 {x}^{4} - 6 {x}^{3} - 53 {x}^{2} + 26x - 20[/tex]
