    This is just a statement. To solve for x, it needs to be an equation.

    I either need what 3x^2+110x+625 is equal to or what x is equal to, if I don't have either of these values, the best I can do is manipulate 3x^2+110x+625, but I won't be able to solve anything

    =0 is not obvious, from negative infinity to positive infinity it could equal *literally* an infinite number of values.

    math. For most algebra courses, they set it to 0 so that they can factor. x intercepts blah blah

    as a student to another student I knew exactly what he/she meant when they said factor it and get the x

    Its been a long time since my algebra course, I guess I've gotten to the point where I assume everything is super complicated, and now I overlook simpler answers.
