Question

Multiply. (q-1)^2

SHOW WORK PLEASE!!!!!!!!!!!!!!

Answer 1

2q^2 - 4q + 2

Explanation:

I'm going to use the FOIL method. FOIL stands for First, Outer, Inner, Last, and is a method used to multiply two binomials.

1. we will start with the First term, which is (q-1) multiplied by itself. This gives us q^2 - 2q + 1.

2. we move on to the Outer term, which is (q-1) multiplied by (q-1). This gives us q^2 - 2q + 1.

3. The Inner term is (q-1) multiplied by q. This gives us q^2 - q.

4. we move on to the Last term, which is q multiplied by (q-1). This gives us q^2 - q.

Now that we have all four terms, we can add them together to get our final answer. Adding all four terms together gives us 2q^2 - 4q + 2. Therefore, the answer to (q-1)^2 is 2q^2 - 4q + 2.

Answer 2

Answer: See explanation

Explanation:

`(q-1)^2\\`

Just as a tip,

`(a-b)^2=a^2-2ab+b^2`

So, subsituting q for a, and b for -1

`q^2-2(-1q)+(-1)^2\\q^2+2q-1`
