Question

Solve each equation by taking square roots 8v^2 +3=35

Answer 1

$8v^2 +3=35$ 

$8v^2=35-3$      $Subtract \ 3 \ from \ both \ sides$

$8v^2=32$ 

$v^2= \dfrac{32}{8}$   $Divide \ both \ sides \ by \ 8$

$v^2=4$ 

$v=+ \sqrt{4}$            $Take \ the \ square \ root \ of \ both \ sides$

$v=+2$                       $\ Since \ 2*2=4, \ the \ square \ root \ of \ 4 \ is \ 2$
