Solve each equation by taking square roots 2n^2 -8=-33

densk [106]

$2n^2 -8=-33$

$
2n^2=-33+8
 
$ $Add \ 8 \ to \ both \ sides$

$2n^2=-25$

$n^2=- \dfrac{25}{2}$ $Divide \ both \ sides \ by \ 2$

$n=+ \sqrt{ -\dfrac{25}{2} }$ $Take \ the \ square \ root \ of \ both \ sides$

$n=+ \sqrt{ \dfrac{5i}{ \sqrt{2}}}$
