Answer:

\underline{\boxed{\sf{2(x - 11)(x + 11)}}}

Step-by-step explanation:

\sf{2x^2 - 242}

<u>Common factor :</u>

\sf{2x^2 - 242}

\sf{2(x^2 - 121)}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

<u>Use the sum-product pattern :</u>

\sf{2(x^2-121)}

\sf{2(x^2 + 11x-11x - 121)}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

<u>Common factor from the two pairs :</u>

\sf{2(x^2 + 11x-11x - 121)}

\sf{2(x(x+11) -11(x + 11))}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

<u>Rewrite in factored form :</u>

\sf{2(x(x+11)- 11(x + 11))}

\sf{2(x - 11)(x + 11)}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

<u>Solution :</u>

\sf{2(x - 11)(x + 11)}

Oof I am really confused on 13. Can someone help me with it? I’ll really appreciate it. Thanks!
Nataly [62]

Hi! I know for sure that a and d are equivalent to the expression which is not what you are looking for. This is because 11 times 8 gives you the 88 on a and if you multiply the 5 also by 8 you get 40 so a is not the answer. The reason I multiply both by the same number and got the equivalency is because, "What you do to one side, you do to the other." Same thing with d. My answer would be B because you can't change the variable to a different number. You can't just give the five the y and make it mean the same. The answer is B.
