Question

Simplifique
a) ab²+b-ab+a-ab²+ab
b) 3x³-2x+y²-2x²+4xy+x³-y²+8x-2xy

Answer 1

A)

$ab {}^{2} + b - ab + a - ab {}^{2} + ab$

${ab}^{2} - ab {}^{2} + b - ab + ab + a$

$b + a$

B)

${3x}^{2} - 2x + y {}^{2} - 2x {}^{2} + 4xy + {x}^{3} - y {}^{2} + 8x - 2xy$

$3x {}^{3} + x {}^{3} - 2x + 8x + y {}^{2} - {y}^{2} - 2x {}^{2} + 4xy - 2xy$

$4x {}^{ 3} + 6x - 2x {}^{2} + 2xy$

Espero ter ajudado!
