49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2

If you mean: -33v = 70-7v then v = 70/-26 Otherwise not knowing the plus, minus or equal value of 70 it has no solution
Multiply out the brackets and collect the like terms which simplifies to 5w-7v
14*13=182
49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2
It can be simplified to: -7v-1096
-102
-12=2+5v+2v ---> Add Like terms-12=2+7v ----> Subtract 2 from both sides-14=7v ---> Divide each side by 7-2=v-2=V is your final answer
the answer is 7v * 5
56v2 + 121v + 63 = 56v2 + 49v + 72v + 63 = 7v*(8v + 7) + 9*(8v + 7) = (8v + 7)*(7v + 9)

644v
If you mean: -33v = 70-7v then v = 70/-26 Otherwise not knowing the plus, minus or equal value of 70 it has no solution
v * 7v > 637*v^2 > 63 v^2 > 9 v < -3 or v > 3.
(6r - 7v)(3r - 2v)
It would just last longer between charges.
