Question

The partial tactonization of x - 3x - 10 is modeled with algebra tiles Which unit tiles are needed to complete the factorization? 2 negative unit tiles 2 positive unit tiles 5 negative unit tiles 5 positive unit tiles

Answer 1

B

Explanation:

Answer 2

(x+2)(x-5)

Explanation:

If it is a quadratic equation as I think it is, else there is no sense, it's possible to see that we need two numbers in such a way its multiplication is -10 and its sum -3 . The only two natural numbers are +2 and -5, therefore the correct factorization is (x+2)(x-5).
