Question

add the following expressions:-
y²-x²,2x²-3y²,5y²-3x²,6x²+2y²​

Answer 1

Answer:

5y²+4x²

Step-by-step explanation:

y²-x²+2x²-3y²+5y²-3x²+6x²+2y²

5y² + 4x²

Answer 2

Answer:

5$y^{2}$ + 4$x^{2}$

Step-by-step explanation:

   y^2-x^2                           (add all of the equations)

-3y^2+2x^2

 5y^2-3x^2

 2y^2+6x^2

=5y^2 + 4x^2

[y-3y=-2y, -2y+5y=3y, 3y+2y=5y]

[-x+2x=x, x-3x=-2x, -2x+6x=4x]
