Given :
![f(x) = {x}^{3} + 2 {x}^{2} + 3x + 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B3%7D%20%20%2B%202%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20%2B%201)
![g(x) = 4x - 5](https://tex.z-dn.net/?f=g%28x%29%20%3D%204x%20-%205)
let's solve for f(x) × g(x) :
![( {x}^{3} + 2x {}^{2} + 3x + 1)(4x - 5)](https://tex.z-dn.net/?f=%28%20%7Bx%7D%5E%7B3%7D%20%20%2B%202x%20%7B%7D%5E%7B2%7D%20%20%2B%203x%20%2B%201%29%284x%20-%205%29)
![4x {}^{4} - 5 {x}^{3} + 8 {x}^{3 } - 10 {x}^{2} + 12 {x}^{2} - 15x + 4x - 5](https://tex.z-dn.net/?f=4x%20%7B%7D%5E%7B4%7D%20%20-%205%20%7Bx%7D%5E%7B3%7D%20%20%2B%208%20%7Bx%7D%5E%7B3%20%20%7D%20%20-%2010%20%7Bx%7D%5E%7B2%7D%20%20%2B%2012%20%7Bx%7D%5E%7B2%7D%20%20-%2015x%20%2B%204x%20-%205)
