Question

(3t5-5t3+11t+3) - (9t5-4t3+2t2-1/2t+3)

Answer 1

$= (3 t^{5} - 5 t^{3} + 11t + 3) - (9 t^{5} - 4 t^{3} + 2 t^{2} - \frac{1}{2}t + 3 ) \\ = 3 t^{5} - 5 t^{3} + 11t + 3 - 9 t^{5} + 4 t^{3} - 2 t^{2} + \frac{1}{2}t - 3 \\ = (3-9)t^{5} + (-5+4)t^{3} + (11+\frac{1}{2})t + (3-3) - 2 t^{2} \\ = -6t^{5} - t^{3} + \frac{23}{2}t - 2 t^{2}$
