Question

Add the following polynomials: 3a3 + 8a - 6 and 4a2 - 9a + 11

Answer 1

Answer:

$3a^3+4a^2-1a+5$

Step-by-step explanation:

Add the following polynomials:

$3a^3 + 8a - 6 \ and\ 4a^2 - 9a + 11$

To add the polynomials we combine like terms

$3a^3 + 8a - 6 + 4a^2 - 9a + 11$

The terms with same variables are like terms

8a and -9a are like terms

8a - 9a = -1a

-6 +11= 5

$3a^3 + 8a - 6 + 4a^2 - 9a + 11=3a^3+4a^2-1a+5$

Answer 2

 3a^3+8a-6
+4a^2-9a+11
=3a^3+4a^2-a+5
