You can solve quadratic equations by using 3 methods-
1- Factorization method in which you have to split middle term to get roots for equation.
![x^{2} - 2x - 8 = 0 \\ x^{2} - 4x + 2x - 8 = 0 \\ x(x - 4) + 2(x - 4) = 0 \\ (x + 2)(x - 4) = 0 x^{2} - 2x - 8 = 0 \\ x^{2} - 4x + 2x - 8 = 0 \\ x(x - 4) + 2(x - 4) = 0 \\ (x + 2)(x - 4) = 0](https://tex.z-dn.net/?f=x%5E%7B2%7D++-+2x+-+8+%3D+0+%5C%5C+x%5E%7B2%7D++-+4x++%2B+2x+-+8+%3D+0+%5C%5C+x%28x+-+4%29+%2B+2%28x+-+4%29+%3D+0+%5C%5C+%28x+%2B+2%29%28x++-+4%29+%3D+0)
x=-2 or x=4
this is factorization method
other 2 are=
2- completing the square
3- quadratic formula
