Simplify sqrt12 - sqrt75 + sqrt147

Like so:

\(\sqrt{12}-\sqrt{75}+\sqrt{147}=\sqrt{3*4}-\sqrt{3*25}+\sqrt{3*49}=(2-5+7)*\sqrt{3}=4\sqrt{3}\)

I think you added the square root of 12 instead of subtracting

Thanks. You're almost right! I added the square root of 75 instead of subtracting it. I've now edited and corrected.
