Question

(4a³ + 5a² - 3a) + (5a3 - 2a² - 4a - 3) = ?​

Answer 1

Answer:

$4a^{3} +5a^{2} -3a+5a^{3} -2a^{2} -4a-3$

$= 4a^{3} +5a^{3} +5a^{2} -2a^{2} -3a-4a-3$

$= 9a^{3} +3a^{2} -7a-3$

Step-by-step explanation:

Answer 2

Step-by-step explanation:

=(4a³+5a²-3a)+(5a³-2a²-4a-3)

=(4a³+5a³+5a²-2a²-3a-4a-3)

=(9a³+3a²-7a-3)
