Open in App

Solution

The required difference is given by
$(- 4 t^{4} + 8 t^{3} - 4 t^{2} - 2 t + 11) - (3 t^{4} - 4 t^{3} + 2 t^{2} - 6 t + 6)$
$- 4 t^{4} + 8 t^{3} - 4 t^{2} - 2 t + 11 - 3 t^{4} + 4 t^{3} - 2 t^{2} + 6 t - 6$
$= (- 4 t^{4} - 3 t^{4}) + (8 t^{3} + 4 t^{3}) + (- 4 t^{2} - 2 t^{2}) + (- 2 t + 6 t) + (11 - 6)$
[grouping like terms]
$= - 7 t^{4} + 12 t^{3} - 6 t^{2} + 4 t + 5$
