Web31 Oct 2024 · Raise both sides of the equal sign to the power that matches the index on the radical. This means square both sides if it is a square root; cube both sides if it is a cube root; etc. It is this step that can introduce extraneous roots if both sides are raised to an even power!! Solve. If the equation still contains radicals, repeat steps 1 and 2. Web17 Nov 2013 · Equality is preserved when one squares both sides. It is also preserved when one takes the square root of both sides (following the convention you mention). But of these two operations, only squaring produces extraneous solutions. If I square both sides of the equation x 2 + x + 1 = x, I get the extraneous solution x = − 1.

Web7 Apr 2024 · x + 2 > x. There are 2 cases: Case 1: x is negative (x < 0) Since LHS is always non negative (it is the principal square root so it is never negative) so this inequality will hold for all values of x. But since under the square root, we cannot have a negative value, (x + 2) >= 0. x >= -2.

WebSo let me explain. Let's assume x is positive. x^2=x*x , of course. But -x*-x=x^2. You can try this with any number. Let's say x^2=y. So the square root of y can be x or -x. The principle, or positive square root of y is x, but -x is the negative square root.(I'm not sure if you're supposed to say it like that, though. It's just how I say it.)
