What is 9x^2 +4x^2 Factor each polynomial completely. If a polynomial is prime,
say so.
Huh? It is 13 x^2
9 of them plus 4 of them is 13 of them.
To factor the polynomial 9x^2 + 4x^2, we can start by looking for common factors. In this case, notice that both terms have a common factor of x^2. We can factor out x^2 from both terms:
9x^2 + 4x^2 = (9 + 4)x^2
Simplifying further, we have:
= 13x^2
Therefore, the polynomial 9x^2 + 4x^2 can be factored completely as 13x^2. Since there are no further factors, we can say that the polynomial is prime.
