Question

Combine like terms.I need help of these can you help me?

Answer 1

Given:

an expression is given as below

`2y^3-4x^2-4-1+3x^2-3y^3-y^3`

Find:

we have to combine like terms.

Step-by-step explanation:

we will combine like terms as follows

`\begin{gathered} 2y^3-4x^2-4-1+3x^2-3y^3-y^3=y^3(2-3-1)+x^2(-4+3)-4-1 \\ =-2y^3-x^2-5 \end{gathered}`

Therefore, the answer is

`-2y^3-x^2-5`
