Question

The diagram represents the factorization of x2 – 9x + 18. It is partially completed.

Answer 1

The correct answers are:

-3x and -6x.

Explanation:

In this model, we multiply the top terms by the terms on the right.  For the box in the top right, we multiply x(x) which gives us x².

For the two missing boxes, we have -3(x) which gives us -3x and -6(x) which gives us -6x.

Answer 2

The answer would be C) –3x and –6x

using the headers for both the top and left side of the diagram, we can see that we need to add a value for when x is multiplied with -3, and when x is multiplied with -6, thus C is our answer
