Question 115417
{{{25x^2=13}}} Start with the given equation



{{{x^2=13/25}}} Divide both sides by 25



*[Tex \LARGE x=\pm sqrt{\frac{13}{25}}] Take the square root of both sides



*[Tex \LARGE x=\pm \frac{sqrt{13}}{sqrt{25}}] Break up the root



*[Tex \LARGE x=\pm \frac{sqrt{13}}{5}] Take the square root of 25 to get 5



So our solution is 


*[Tex \LARGE x=\pm \frac{sqrt{13}}{5}] 



which basically means


*[Tex \LARGE x=\frac{sqrt{13}}{5}] or *[Tex \LARGE x=- \frac{sqrt{13}}{5}]
