To determine the simplified form of the polynomial below:
[tex](3x^2-4x+6x)+(5x^3+2x^2-3x)[/tex]Step 1: Open the bracket
[tex]\begin{gathered} (3x^2-4x+6x)+(5x^3+2x^2-3x) \\ 3x^2-4x+6x+5x^3+2x^2-3x \end{gathered}[/tex]Step 2: Collect like terms and add up
[tex]\begin{gathered} 3x^2-4x+6x+5x^3+2x^2-3x \\ 5x^3+3x^2+2x^2-4x+6x^{}-3x \\ 5x^3+5x^2-x \end{gathered}[/tex]Therefore the simplified form is
[tex]5x^3+5x^2-x[/tex]Hence the correct answer is
