What is the question you are struggling with I will try and help.
(13x+14)(6x-5)=0
78x²-65x+84x-70=0
78x²+19x-70=0
It was equation.
______________
Factoring⇒ a×c=78×(-70)=-5460
84×(-65)=-5460
84+(-65)=19 which is b

78x²+84x-65x-70=0
6x(13x+14)-5(13x+14)=0
(13x+14)(6x-5)=0
13x+14=0 6x-5=0
13x=-14 6x=5
x=-14/13 x=5/6
Two solution X=-14/13;5/6

Answer:
Top Row:20,20
Bottom Row:26,26
Step-by-step explanation:
2(3m+7) when m is 1. Plug in to get: 2 (3*(1) + 7)=20
6m+14 when m is 1. Plug in to get: 6*(1) + 14=20
2(3m+7) when m is 2. Plug in to get: 2 (3*(2) + 7)=26
6m+14 when m is 2. Plug in to get: 6*(2) + 14=26
