[tex]10p^2 +20=1490[/tex]  

[tex] 10p^2=1490-20 [/tex]        [tex]Subtract \ 20 \ from \ both \ sides[/tex]

[tex]10p^2=1470 [/tex] 

[tex]p^2= \dfrac{1470}{10} [/tex]         [tex]Divide \ both \ sides \ by \ 10[/tex]

[tex]p^2=147[/tex] 

[tex]p=+ \sqrt{147} [/tex]       [tex]Take \ the \ square \ root \ of \ both \ sides[/tex]

[tex]p=+7 \sqrt{3} [/tex]
