The product of three less than a number and eight is nine

[see below]

Step-by-step explanation:

Three less than a number (x) would be: x - 3

"The product of three less than a number and eight" would be 8(x-3).

The product of three less than a number and eight is nine would be:

8(x-3) = 9

Hope this helps.

(x-3) (x+2)

Step-by-step explanation:

x^2 - x - 6

What 2 numbers multiply to -6 and add to -1

-3 *2 = 6

-3+2 = -1

(x-3) (x+2)
