## anonymous 5 years ago What are the square roots of 0=9x^2-49 explain plz

1. anonymous

Start by adding 49 to both sides, you get $$9x^2=49$$, and then divide both sides by 9, which gives $$x^2= \frac{49}{9}$$. Taking the square roots of both sides gives the two solutions $$x= \frac{7}{3}$$ and $$x= -\frac{7}{3}$$.
