One Thing I learned this week was how to multiply binomials using area models which is basically simplifying it using 4 boxes, for example.
as you see we use the 4 boxes, we first put the numbers on the side and we multiply the number that are outside the box and put the answer in the box in between them. on the top of the box I wrote which number are being multiplied.
after you have all your numbers in the boxes, make sure you combine all the like terms, for example I underlined 35x and 8x because they are like terms that can be added together, In the end you should end up with your answer, the answer I got for my question is 142 + 43x + 20.
