Question

x²+2xy-y²=0 plz answer of this question

Answer 1

Step-by-step explanation:

x² + 2xy - y² = 0

=> (x - y)² = 0

=> x - y = 0 ( squaring both the sides )

=> x = y

Now, if we substitute the value x = y in the equation, we get,

x² + 2x × x - x² = 0

=> 2x² = 0

=>x² = 0

=> x = 0

Hence, x=0 and y=0
