Question

Urgente! (3a³ -2a³b +5ab² –6b³) + (7a2² b - 5a³ - b³ +5ab² –6ab²)

Answer 1

Oie, Td Bom?!

$(3a {}^{3} - 2a {}^{2} b + 5ab - 6b {}^{3} ) + (7a {}^{2}b - 5a {}^{3} - b {}^{3} + 5ab {}^{2} - 6ab {}^{2} )$

$3a {}^{3} - 2a {}^{2} b + 5ab - 6b {}^{3} + (7a {}^{2} b - 5a {}^{3} - b {}^{3} - ab {}^{2} )$

$3a {}^{3} - 2a {}^{2} b + 5ab - 6b {}^{3} + 7a {}^{2} b - 5a {}^{3} - b {}^{3} - ab {}^{2}$

$- 2a {}^{3} + 5a {}^{2} b + 5ab - 7b {}^{3} - ab {}^{2}$
