Question

hola ayud aporfavor​

Answer 1

$8a + 9b - 3a - 5b \\ = 5a + 4b$

$18m^2 - 9m - 5m^2 \\ = 13m^2 - 9m$

$18x + 11y - 9x - 4y \\ = 9x + 7y$

$19m - 10m + 6m - 12n \\ = 15m - 2n$

$5a + 8a - a - 6a \\ = 6a$

$5ax^2 - 3a^2y + ( \frac{6}{4})ax^2 \\ = \frac{13}{2} ax^2- 3a^2y$

$m^6 + ( \frac{2}{3} )m^4 + 3m^4 \\ = m^6 + \frac{11}{3} m^4$
