Question

Simplifique as expressões algébricas.
a) 8x - 5x + 2x
b)6t² - 4t² - 2t²
c) 3abc - 2abc + 7abc
d) - 6m - 3m - 4m²

Answer 1

Resposta:

a) 5x

b) 0

c) 8abc

d) -m x ( 9+4m )

Explicação passo-a-passo:

$a)8x - 5x + 2x =$

$(8 - 5 + 2) x$

$5x$

$b){6t}^{2} - {4t}^{2} - {2t}^{2}$

$(6 - 4 - 2) {t}^{2}$

$0 {t}^{2} = 0$

$c)3abc - 2abc + 7abc$

$(3 - 2 + 7)abc$

$8abc$

$d) - 6m - 3m - {4m}^{2}$

$- 9m - {4m}^{2}$

$- m \times (9 + 4m)$
