Question

answer if you are sure why do we equate polynomials by 0 ??​

Answer 1

Answer:

It's simply a way of putting an equation into a standard form. You can always add and subtract the same quantities from both sides so that one of the sides becomes zero without changing the solution(s) of the equation. By equating the polynomial equation to zero and factoring the polynomial, we can find its roots.

Answer 2

Answer:

you might have noticed that when we want to solve any equation, we tend to set it equal to zero. This is because of the zero product property. The property states that if ,then either or (or both).
