You can put this solution on YOUR website! (6t3-3t2+t-[(t3+3t2-3)-(3-t)] remove the () around the (t^3+t^2-3) & the -(3-t) terms. Be sure to change the signs within the -(3-t) term
6t^3-3t^2+t-[t^3-3t^2+3-3+t] Remove the [] signs remembering to change all the signs within the brackets.
6t^3-3t^2+t-t^3+3t^2-3+3-t Now combine all like terms.
6t^3-t^3-3t^2+3t^2+t-t+3-3 Now cancel out the 3t^2 terms, the t terms & the 3 terms which leaves:
6t^3-t^3=5t^3 ans.
