Question

14x

X (14-x)

X (14+x)

(14-x)(14+x)

(X+14)(x-14)

Answer 1

Hi, Jonathan.

 

If the sum of two numbers is 14, and one number is x, the other number must be 14 - x. Then, when the two numbers are added, we get x + 14 - x, which is just 14.

 

So, the product of the two numbers is x(14 - x).
