![]() ![]() Of negative four x minus four, but this still doesn't help you. And you could get something like this, you would get x is equal to plus or minus the square root The plus of minus of one side to make sure you're Square root of x squared is equal to, and you could try to take And now, someone might say, if I take the square root of both sides, I could get, I'll just write that down. And then what happens? On the left hand side, you do indeed isolate the x squared, and on the right hand side, you get negative four x minus four. Isolate that x squared by subtracting four x from both sides and subtracting three from both sides. So you could imagine, let me just rewrite it. People will try to go for is to isolate the x squared first. So just willy nilly, taking the square root ofīoth sides of a quadratic is not going to be too helpful. Isolate the x over here? You've pretty quickly hit a dead end. But even if this wasĪ positive value here, how do you simplify or how do you somehow Even if this wasn't a negative one here, that's the most obvious problem. Plus four x plus three is equal to the square The square root of both sides? And if you did that, you would get the square root of x squared So one strategy that people might try is, well, I have something squared, why don't I just try to take I have something on both sides of an equal sign. Why is it a quadratic equation? Well, it's a quadratic because it has this secondĭegree term right over here and it's an equation because ![]() In this video, we're gonna talk aboutĪ few of the pitfalls that someone might encounter while they're trying to solve a quadratic equation like this. ![]()
