- Inequality proof, why isnt squaring by both sides permissible?
If we have x <2 then we can't square both sides, because squaring both sides is a special case of multiplying both sides by the same thing, and if x <2 then x and 2 are not equal If x <2 then x2 <4 is true if x is, for example, 1, and x2 <4 is false if x is, for example, − 3

- Why can I square both sides? - Mathematics Stack Exchange
I am not used to English I ask for your understanding in advance There is the equation: x = 21 2 x = 2 1 2 we can square both side like this: x2 = 2 x 2 = 2 But I don't understand why that it's okay to square both sides What I learned is that adding, subtracting, multiplying, or dividing both sides by the same thing is okay For example: x = 1 x = 1 x − 1 = 1 − 1 x − 1 = 1 − 1 x −
- algebra precalculus - How to square both the sides of an equation . . .
0 You can square both sides of the equation the way you did But there is a problem in the third line of your working You had x4(x + 3) = (x + 3)3 x 4 (x + 3) = (x + 3) 3 and then divided both sides by (x + 3) (x + 3) to get x4 = (x + 3)2 x 4 = (x + 3) 2 This is a problem because you are losing solutions to the overall equation
- Why cant you square both sides of an equation?
So, when you square both sides of an equation, you can get extraneous answers because you are losing the negative sign That is, you don't know which one of the two square roots of the right hand side was there before you squared it
- geometry - Compass-and-straightedge construction of the square root of . . .
The ability to construct a straight line in any direction from any starting point with the "unit length", or the length whose square root of its magnitude yields its own magnitude Is there a way to geometrically construct (using only a compass and straightedge) the a line with the length of the square root of the arbitrary-lengthed line?
