Question

Add the polynomials. (9x² - 4x) + (6x²-x)

Answer 1

The sum of the polynomials is;

$15x^2-5x$

Here, we want to add the given polynomials

We can do this by adding the similar terms together;

$\begin{gathered} (9x^2-4x)+(6x^2-x) \\ 9x^2-4x+6x^2_{}-x \\ 9x^2+6x^2-4x-x \\ 15x^2-5x \end{gathered}$
