in this problem I have. Why squared over nine minus X squared equals one again. I cannot enter these into my calculator the way that it is because we could only do why equals sub. I'm going to end up with two equations and you'll see why in just a second I'm gonna solve this equation for why? So the first thing I'm going to do is add X squared to both sides. I'm then going to multiply both sides by nine. So why squared equals nine times one plus expert and I'm not gonna fall climb out, actually gonna leave it like this When I take the square root of both sides, I'm going to get plus or minus the square root of this whole mess. Well, the squared of nine is just three and then the square root of one plus x squared. You cannot simplify that because it's a some and it's not a perfect square. Therefore, an equation one of would enter three times one plus x squared an equation to will be the opposite of three times square toe one plus X squared. These would be the two equations that I would need to enter it
