Answer:
49x²-16 = (7x - 4)(7x + 4)
Step-by-step explanation:
Your "49×2-16" is incorrect; did you mean "49x^2-16" or "49x²-16?"
This last expression is the difference of two squares.
The formula for that is a² - b² = (a - b)(a + b), and so your 49x²-16 factors as follows:
49x²-16 = (7x - 4)(7x + 4)

The Solution:
Given:
Each withdrawal by Brandon = $x
ATM charge per transaction = $2
Required:
To find an expression for Brandon's total withdrawal if he withdraws the same amount once a week for 7 weeks.
Step 1:
We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.
![\text{ Each withdrawal=x+2=\$(x+2)}](https://tex.z-dn.net/?f=%5Ctext%7B%20Each%20withdrawal%3Dx%2B2%3D%5C%24%28x%2B2%29%7D)
Step 2:
Finding the required total amount, we have:
![\text{ Total amount withdrawn=7(x+2)=\$7(x+2)}](https://tex.z-dn.net/?f=%5Ctext%7B%20Total%20amount%20withdrawn%3D7%28x%2B2%29%3D%5C%247%28x%2B2%29%7D)
![\begin{gathered} 7(x+2) \\ or \\ 7x+14 \\ \text{ or} \\ 7\mleft(x\mright)+7\mleft(2\mright) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%207%28x%2B2%29%20%5C%5C%20or%20%5C%5C%207x%2B14%20%5C%5C%20%5Ctext%7B%20or%7D%20%5C%5C%207%5Cmleft%28x%5Cmright%29%2B7%5Cmleft%282%5Cmright%29%20%5Cend%7Bgathered%7D)
Therefore, the correct answers are: [options 2, 3, and 4]
