Can someone tell me the answer to this question and explain why or why not all equations of parabolas can be expressed in factored form?

some equations are not factorable. in this case you have to leave in its

y=ax^2+bx+c form

Yes, they can be.
If they are of the form y=ax^2+bx+c, by completing the square, they can be expressed as y=d(x-h)^2+k, where (h,k) is the vertex.
Conversely, if they are of form y=d(x-h)^2+k, they can be expressed as
y=ax^2+bx+c by expanding the vertex form to the quadratic form.

All equations of parabolas cannot be expressed in factored form.  Sometimes, the roots of quadratic equations are irrational or imaginary.  Therefore, it will not be possible for the equation to be factored so it will not be possible to express it in factored form.

YES! but NOT in a binomial form like, (x-1)(x+1)..

we just did parabolas as our last unit in precal and the teacher NEVER showed us a parabola in a binomial factored form just like the one above.  Is was usually/always in y=a(x-h)² +k  where "a" cannot equal to zero and (h,k) is the vertex

i think if it was in a binomial factored form, you're looking for zeros
