Question

Simplify (3x³ + 8x² – 2x + 4) + (6x² + 4x + 4).

Answer 1

3x³ + 16x² + 2x + 8

Explanation:

We have the following expression:

`\left(3x^3+8x^2-2x+4\right)+\left(6x^2+4x+4\right)`

We solve and simplify in the following way:

`\begin{gathered} 3x^3+8x^2-2x+4+6x^2+4x+4 \\ \\ \text{ We group like terms:} \\ \\ (3x^3)+(8x^2+6x^2)+(-2x+4x)+(4+4) \\ \\ 3x^3+14x^2+2x+8 \end{gathered}`
