Step-by-step explanation:
[tex](2x^2-6x^3+4)+(2x^3+3x^2+4)[/tex]
Since this is addition, you can just easily combine the terms.
[tex](2x^2+3x^2)+(-6x^3+2x^3)+(4+4)[/tex]
[tex]5x^2 -4x^3+8[/tex]
Now, all we have to do is put it in standard form meaning the exponents have to go in descending order. Largest exponent to smallest exponent.
[tex]-4x^3+5x^2+8[/tex]
So, this is your answer in standard form.
