Using the FOIL method, we can solve for (x - 2)(x - 3)
First, Outside, Inside, Last
x(x) = x²
x(-2) = -2x
x(-3) = -3x
-2(-3) = 6
x² - 2x - 3x + 6 = x² - 5x + 6
since it is suppose to be 6 positive boxes (+) instead of six negative boxes (-), i believe your answer is: B, even though i'm not all that sure how the boxes work. But choose the answer that will help you get x² - 5x + 6
hope this helps
