(2x^2 - 5x + 2) + (x^2 - 2x + 5)

= 2x^2 - 5x + 2 + x^2 - 2x + 5

= 3x^2 - 7x + 7

= 2x^2 - 5x + 2 + x^2 - 2x + 5

= 3x^2 - 7x + 7

(4x^2 + 3x + 2) - (2x^2 + 2x + 1)

= 4x^2 + 3x + 2 - 2x^2 - 2x - 1

= 2x^2 + x + 1

= 4x^2 + 3x + 2 - 2x^2 - 2x - 1

= 2x^2 + x + 1

(-6x + 2y -3) - (2x - 4y - 7)

= (-6x + 2y - 3) + (-2x + 4y + 7)

= -8x^2 + 6y + 4

= (-6x + 2y - 3) + (-2x + 4y + 7)

= -8x^2 + 6y + 4
