Find the product of following: \( \begin{array}{ll}\text { (a) }\left(x^{3}-4 x+8\right)(3 x+4) & \text { (b) }\left(-x^{2}-3 x+9\right)(-4 x-7) \\ \text { (c) }\left(9 x^{2}-x+15\right)\left(x^{3}-5\right) & \text { (d) }\left(x^{2}-2 x y-y^{2}\right)(x+y) \\ \text { (e) }\left(x^{2}-x y+y^{2}\right)(x+y) & \text { (f) }\left(x^{2}-2 x y+y^{2}\right)(x-y) \\ \text { (g) }(2 x+3 y-5)(x-y+2) & \text { (h) }\left(x^{2}+x y+y^{2}\right)(x-y) \\ \text { (i) }\left(\frac{5}{4} x^{3}-\frac{7}{6} x^{2}+\frac{3}{2} x\right)(x+y) & \text { (j) }\left(-2 x^{2}-3 x-7\right)\left(-3 x^{2}-5 x-4\right) \\ \text { (k) }\left(x^{2}-5 x+18\right)\left(x^{2}+2 x-13\right) & \end{array} \)
