Question

justify whether following equation is quadratic equation (x+2)^2=x^2​

Answer 1

Thanks for your question...

Your required answer :

• Not Quadratic

Given :

• ( x + 2 )² = x²

To Justify :

• Whether the equation is Quadratic or not.

Solution :

• ( a + b )² = a² + b² + 2ab

Now ,

• x² + 4 + 8x = x²
• x² - x² + 4 + 8 x = 0
• 8x + 4 = 0

As we can see that there is no variable with degree as 2 , So the following equation is not Quadratic.

Not Quadratic

Given :

( x + 2 )² = x²

To Justify :

Whether the equation is Quadratic or not.

Now ,

x² + 4 + 8x = x²

x² - x² + 4 + 8 x = 0

8x + 4 = 0

As we can see that there is no variable with degree as 2 , So the following equation is not Quadratic.
