What is the product of (x - 9) and (2x - 7)

Step-by-step explanation:

You have to multiply both terms from the first one by both term in the second on, it'll look like this:

Once you combine like terms it'll be the final

You can use foiling to get any other questions like this:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
