Question

X^2-X^2=X^2-X^2
X(X-X)=(X+X)(X-X)
Cancel both the (X-X)
1X=2X
1=2
Prove this wrong

Answer 1

Answer:

0 = 0

Step-by-step explanation:

x² - x² = x² - x²

0 = 0

Answer 2

Answer:

Step-by-step explanation:

It's wrong

Let's under stand it by an example, say x= 7

So by the given equation 7(7–7) = (7–7)(7+7)

Which is effectively 7(0)=(0)(14)

Now the part comes where you made a mistake if you are saying that x=2x since you cannot divide both the sides by 0 (x-x=0)

So remember you can only cancel a similar term on both sides of the equation if you are sure that the term is a non zero quantity
