Is y=(2x+5)(3x-7) considered factored form of a quadratic?

Factored form is stated as y=a(x-s)(x-t) so y=(2x+5)(3x-7) should be written as y=6(x+5/2)(x-7/3) to be in “proper” factored form.

I'm trying to determine if y=(2x+5)(3x-7) would be considered to be in factored form.

There may not be a definitive answer to this so feel free to offer your opinion.

If anyone knows of a credible site that has a definitive answer that would be great.

Thanks

It's a function y, of the independent variable, x. The function is in factored form. If you have that y=0,
then the resulting quadratic equation is 0=(2x+5)(3x-7), obviously still in factored form. This may be overly picky.
