Question

Add the expression by column method

5a³-3a+7,7a³-11a²+4a-3 and 2a²-11
​

Answer 1

Step-by-step explanation:

We have to add the following:

$5a {}^{3} - 3a + 7 + 7a {}^{3} - 11a {}^{2} + 4a - 3 + 2a {}^{2} - 11$

Now, we have to add the like terms

$12a {}^{3} - 9a {}^{2} + a - 7$

This is the solution
