Question

tell whether the equation x(x+2)-x^2+y(y-3)-y^2=0 is an equation of linear equation of two variables or not​

Answer 1

Step-by-step explanation:

x(x+2)-x²+y(y+3)-y²=0

x²+2x-x²+y²+3y-y²=0

2x + 3y = 0

YES IT IS

Answer 2

Answer:

x(x+2) - x² + y(y-3) -y²

= x² + 2x - x² + y² - 3y - y²

As the 2nd degree terms(x² & y²) cancel out, the equation becomes

2x - 3y

So, this is a linear equation in two variables.
