49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2
7v -14 = -7

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
49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2
7v -14 = -7
v * 7v > 637*v^2 > 63 v^2 > 9 v < -3 or v > 3.
It can be simplified to: -7v-1096
-102
the answer is 7v * 5
56v2 + 121v + 63 = 56v2 + 49v + 72v + 63 = 7v*(8v + 7) + 9*(8v + 7) = (8v + 7)*(7v + 9)

Volume of a cylinder = πr²hV= 3.14159 × (3)² × 7V= 197.92 ft³
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
There is no solution, as it is not an equation. However it could be simplified to: -18v - 86 or -2(9v + 43)
