![{50x}^{2} + 30x + 10](https://tex.z-dn.net/?f=%20%7B50x%7D%5E%7B2%7D%20%20%2B%2030x%20%2B%2010)
• first factorise out 10:
![= 10(5 {x}^{2} + 3x + 1)](https://tex.z-dn.net/?f=%20%3D%2010%285%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20%2B%201%29)
• then find factors of the quadratic equation in the bracket:
