Answer 1

\(\Large\bf \color{royalblue}{\text{Welcome to OpenStudy! :)}}\)

Answer 2

\[\Large\bf\sf t^2(t+1)-t(2t^2-1)\]

Answer 3

So you'll start by distributing some stuff.

Answer 4

\[\Large\bf\sf \color{orangered}{t^2}(t+1)-t(2t^2-1)\quad=\quad t\cdot\color{orangered}{t^2}+1\cdot\color{orangered}{t^2}-t(2t^2-1)\]Which simplifies to,\[\Large\bf\sf t^3+t^2-t(2t^2-1)\]We distributed the t^2 to each term in the first set of brackets.
Understand how that works?
Think you can do it with the other set of brackets?
You have to distribute a -t to each term so it's a little trickier.
