Question

simplifique os polinômios na forma reduzida

$a)10x {}^{2} + 7xy + 4xy - 10x {}^{2}$
$b)5a {}^{3} + 2b {}^{5} - 6 + c {}^{2} - 3 {a}^{3} + 4$
$c)(12a - 3b) + 2a + 5b - 6$
$d)(2x {}^{2} + 3xy) - (11xy + 22y) + 2x {}^{2}$

Answer 1

Olá, boa noite!

a)
$10 x^{2} +7xy-10 x^{2}$
7xy+4xy
11xy

b)
$5 a^{3} +2 b^{5} -6+ c^{2} -3 a^{3} +4$
$2 a^{3} +2 b^{5} -2+ c^{2}$

c)
(12a-3b)+2a+5b-6
12a-3b+2a+5b-6
14a+2b-6
2(7a+b-3)

d)
$(2 x^{2} +3xy)-(11xy+22y)+2 x^{2}$
$2 x^{2} +3xy-11xy-22y+2 x^{2}$
$4 x^{2} -8xy-22y$
$2(2 x^{2} -4xy-11y)$

Espero que tenha ajudado.
