But if we were to do this, we would get x is equal to x, and then we could subtract x from both sides. X minus five times five X plus two, when does that equal zero? And like we saw before, well, this is just like what we saw before, and I encourage you to pause the video, and try to work it out on your own. Sometimes in math we describe an expression with a phrase. X 1/2 = root x so when you see x 2/2 is the same as (root x) 2 or root (x 2 )so it does make sense. What is x times x in algebra? (x^2 or 2x). Calculate the pH of a solution of 0. Watch Super Bowl LVII live on.
