Question

the sum of x-2y ,x² + y,2x² + y - x is _____​

Answer 1

Answer:

3x²

Step-by-step explanation:

The sum is = (x - 2y + x² + y + 2x² + y - x) = (x - x) + (- 2y + y + y) + (x² + 2x²) = 3x²

Answer 2

Answer:

solution:- x - 2y + x^2 + y + 2x^2 + y - x

= x - x - 2y + y + y + x^2 + 2x^2

= 0 - 2y + 2y + 3x^2

= 3x^2 Ans.
