Question

Reduza os termos semelhantes:
Modelo: 5x + 3x – 2x = 6x
a) 10a + 2a =
b) 9x – 5x =
c) 4y²- 9y² =
d) 6a² - a² =
e) 3y – 6y =
f) -4m²+ 12m² =

Answer 1

$a) \: 10a + 2a$

$10a + 2a$

$\boxed{\orange{12a}}$

$b) \: 9x - 5x$

$9x - 5x$

$\boxed{\orange{4x}}$

$c) \: 4 {y}^{2} - 9 {y}^{2}$

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

$\boxed{\orange{ - 5 {y}^{2} }}$

$d)6 {a}^{2} - {a}^{2}$

$6 {a}^{2} - {a}^{2}$

$\boxed{\orange{5 {a}^{2} }}$

$e) \: 3y - 6y$

$3y - 6y$

$\boxed{\orange{ - 3y}}$

$f) \: - 4 {m}^{2} + 12 {m}^{2}$

$- 4 {m}^{2} + 12 {m}^{2}$

$\boxed{\orange{8 {m}^{2} }}$

Espero ter ajudado!
