"Web13 May 2024 · Since square roots are non-negative, inequality (2) is only meaningful if both sides are non-negative. Hence, squaring both sides was indeed valid. What property justifies squaring both sides of an equation? The two sides of the equation are equal, so doing the same thing to each side results in two new, equal values.

For example, three squared is nine (3 2 = 9), so the square root of nine is three. In symbols, this is. \sqrt {9} = 3 9 = 3. The “√” symbol tells you to take the square root of a number, and you can find this on most calculators. 00:00 00:00.

WebSquare both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation creates them. 1 comment ( 23 votes) Upvote http://www.lkozma.net/inequalities_cheat_sheet/ineq.pdf

WebVisual proof that (x + y)2 ≥ 4xy. Taking square roots and dividing by two gives the AM–GM inequality. [1] In mathematics, the inequality of arithmetic and geometric means, or more briefly the AM–GM inequality, states that the arithmetic mean of a list of non-negative real numbers is greater than or equal to the geometric mean of the same ... 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.)
