Question

Use the FOIL method to find the product. Express the product in descending powers of the variable.

(7+6x)(1-5x)

Answer 1

Answer down below!

To begin with, the FOIL method stands for First Outside Inside Last. This is the method we use to multiply numbers like this

So, how do we start?

First: 7 times 1
Outside: 7 times 5x
Inside: 6x times 1
Last: 6x times 5x

7 times 1 = 7
7 times 5x = 35x
6x times 1 = 6x
6x times 5x = 30x^2

Now, with all these numbers, we combine all like terms

Our final answer will be 30x^2 + 41x +7
