<h2>
![20 {x}^{3} - 36 {x}^{2} + 7x + 3](https://tex.z-dn.net/?f=20%20%7Bx%7D%5E%7B3%7D%20%20-%2036%20%7Bx%7D%5E%7B2%7D%20%20%2B%207x%20%2B%20%203)

Solution,
![(5x + 1)(2x - 1)(2x - 3)](https://tex.z-dn.net/?f=%285x%20%2B%201%29%282x%20-%201%29%282x%20-%203%29)
![= 5x(2x - 1) + 1(2x - 1) \times (2x - 3) \\ = (10 {x}^{2} - 5x + 2x - 1)(2x - 3) \\ = (10 {x}^{2} - 3x - 1)(2 x - 3) \\ = 10 {x}^{2} (2x - 3) - 3x(2 x - 3) - 1(2x - 3) \\ = 20 {x}^{3} - 30 {x}^{2} - 6 {x }^{2} + 9x - 2x + 3 \\ = 20 {x}^{3} - 36 {x}^{2} + 7x + 3](https://tex.z-dn.net/?f=%20%3D%205x%282x%20-%201%29%20%2B%201%282x%20-%201%29%20%5Ctimes%20%282x%20-%203%29%20%20%20%5C%5C%20%20%3D%20%2810%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20%2B%202x%20-%201%29%282x%20-%203%29%20%5C%5C%20%20%3D%20%2810%20%7Bx%7D%5E%7B2%7D%20%20-%203x%20-%201%29%282%20x%20-%203%29%20%5C%5C%20%20%3D%2010%20%7Bx%7D%5E%7B2%7D%20%282x%20-%203%29%20-%203x%282%20x%20-%203%29%20-%201%282x%20-%203%29%20%5C%5C%20%20%3D%2020%20%7Bx%7D%5E%7B3%7D%20%20-%2030%20%7Bx%7D%5E%7B2%7D%20%20-%206%20%7Bx%20%7D%5E%7B2%7D%20%20%2B%209x%20-%202x%20%2B%203%20%5C%5C%20%20%3D%2020%20%7Bx%7D%5E%7B3%7D%20%20-%2036%20%7Bx%7D%5E%7B2%7D%20%20%2B%207x%20%2B%203)
