Question

How is it possible that the sum of two quadratic trinomials is a linear​ binomial?

Answer 1

Answer:

Follows are the responses to this question:

Step-by-step explanation:

In this question, if both quadratic trinomials include opposite $x^2$ terms of signs, it's indeed possible that's also possible, which is why the quadratic $x^2+2x +1 \ and \ -x^2 + 4x -5$ cancels the  $x^2 \ to\ 6x- 4$, which would be a linear binomial.  that's why this statement is true that the "two quadratic trinomials have $x^2$ -terms in signs opposite".
