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)}

joanne cannot decide which of two washing machines to buy. The selling price of each is ​$660. The first is marked down by ​40%.
Alexxx [7]

Answer: The first machine would cost $420

and the second machine would cost $432

you should buy the first machine

Step-by-step explanation:If you get a 30% discount, then you are paying 70% of the selling price.

Machine 1:  600(.70) = 420

Machine 2:  A 10% discount means you pay 90%

600(.90) = 540   But now you get a 20% discount on that amount, which means you would pay 80%

So, 540(.80) = 432
