I'll be honest, I don't know if you are right in the beginning. I can, however, tell you how to continue from 4x^2=100, if you are right up until that point. 4x^2=100 Divide both sides by 4. x^2=25 Take the square root of both sides. x=+-5

A fact is something that can be proven to be true. Examples: the sky is blue, 12*10=120, the capital of NJ is Trenton. We can check on any of these things if we do not know. An opinion is something that cannot be proven. Examples: blue is the best color, that shirt is nice. (...
