2)Completing the square method
3)Formula method.

Quadratic equation is always in the form
ax² +bx +c=0

The 3 methods used in solving quadratic equation are sometimes used interwovenly depending on the equation. Sometimes Factorization method can't be used to solve some equation but such equation always work with formula method and quadratic formula method.
