Question

(3.3a - 0.4b) + (5.1a + 0.4b) = add the polynomials

Answer 1

Adding and simplifying the polynomial will give;

`8.4a`

Step-by-step explanation:

Given the polynomial;

`(3.3a-0.4b)+(5.1a+0.4b)`

Removng the brackets and simplifying we have;

`\begin{gathered} 3.3a-0.4b+5.1a+0.4b \\ 3.3a+5.1a-0.4b+0.4b \\ 8.4a+0 \\ =8.4a \end{gathered}`

Adding and simplifying the polynomial will give;

`8.4a`
