<em>Answer : </em>

C

<em>Step-by-step explanation:</em>

  • (a+b)(a-b) = a² - b²  
  • a( b + c) = ab + ac
  • a (b - c) = ab - ac
  • a( b + c) + d( b + c) = (a + d) (b + c)

<em>3x – 5 + 23x – 9</em> = 26x - 14

2 . 13x = 26x

2. -7 = -14

2 ( 13x -7) <em><u>so answer is C</u></em>

<em><u>or another way :</u></em>

<em>a. 2(14x -6)  = </em>28x - 12

<em>b. 3x(13x-6)  = </em>39x² - 18x

<em>c. 2(13x -7)  = </em>26x - 14

<em>d. 3x(13x - 5) = </em>39x² -15x

so answer is C

Hope this helps ^-^
