Answer 2

I am going to give you a tip.

\(\large\color{midnightblue}{ \rm (4x^3 + 2x^2 - 4x + 3)+(7x^3 -4x^2 + 7x + 8) }\) this is same as,

\(\large\color{midnightblue}{ \rm 4x^3 + 2x^2 - 4x + 3+7x^3 -4x^2 + 7x + 8 }\)


\(\large\color{royalblue}{ \rm 4x^3 \color{red} { + 2x^2 } \color{green} { - 4x } \color{black} {+3 }+7x^3\color{red} {-4x^2 } \color{green} { + 7x } \color{black} { +8 } }\)
