What characteristics are an indicator that the factoring method could be used to solve the quadratic? Select all that apply.

• b=0 so the bx term is not in the equation

• there is a perfect square trinomial given

• a=1, b is even, and there's a non-zero number on the other side

• the expression can be easily factored
