Answer 1

Simplify, write in standard form.
t^2(t + 1) – t(2t^2 – 1)

Answer 2

Expand each bracket in turn

Remove the brackets - making SURE you take into account the MINUS sign

Combine all the terms having x^3, x^2, x and constants together to give standard form

Answer 3

Like this? -t^3 + t^2 + t
