b)3x-6y+4+4x+2y-2=

Answer 1

a) 3X² + 8X - 10

B) 7X - 4Y + 2

Answer 2

Oie, Td Bom?!

a)

$= 5x {}^{2} + 5x - 8 - 2x {}^{2} + 3x - 2$

$= 3x {}^{2} + 5x - 8 + 3x - 2$

$= 3x {}^{2} + 8x - 8 - 2$

$= 3x {}^{2} + 8x - 10$

b)

$= 3x - 6y + 4 + 4x + 2y - 2$

$= 7x - 6y + 4 + 2y - 2$

$= 7x - 4y + 4 - 2$

$= 7x - 4y + 2$
