## anonymous one year ago Solve 4x^2=28 by finding square roots. Please show me how to solve this by including the steps.

1. zzr0ck3r

first divide both sides by 4, and tell me what you have.

2. anonymous

x^2=7

3. zzr0ck3r

ok now take the square root of both sides and tell me what you have

4. anonymous

x= 2.64

5. anonymous

?

6. zzr0ck3r

well, you should have gotten $$x=\pm \sqrt{7}$$ So $$x=\sqrt{7}$$ or $$-\sqrt{7}$$
