What methods has your class covered for solving quadratic equations?

 

[HallsofIvy]

Methods for solving quadratic equations:
1) Factor
2) Complete the square
3) Quadratic Formula

Not all quadratics can be factored (with integer coefficients) but this one can. Lool for two integers whose product is 27 and whose sum is 12.
