[tex]8v^2 +3=35 [/tex]
[tex]8v^2=35-3
[/tex] [tex]Subtract \ 3 \ from \ both \ sides[/tex]
[tex]
8v^2=32
[/tex]
[tex]v^2= \dfrac{32}{8} [/tex] [tex]Divide \ both \ sides \ by \ 8[/tex]
[tex]v^2=4[/tex]
[tex]
v=+ \sqrt{4}
[/tex] [tex]Take \ the \ square \ root \ of \ both \ sides[/tex]
[tex]
v=+2
[/tex] [tex]\ Since \ 2*2=4, \ the \ square \ root \ of \ 4 \ is \ 2[/tex]
