Question

ADD
(t³+5t²-12t) and (2t³-15t²+4t)​

Answer 1

Answer:  ( t^3+5t^2-12t) + (2t^3-15t^2+4t)

              = t^3+5t^2-12t+2t^3-15t^2+4t

              = 3t^3-10t^2-8t^2

Answer 2

Solution :-

$\sf : \implies {t}^{3} + {5t}^{2} - 12t + {2t}^{3} - {15t}{2} + 4t$

$\sf : \implies (1 + 2) {t}^{3} + (5 - 15) {t}^{2} + ( -12 + 4)t$

$\sf : \implies {3t}^{3} - {10t}^{2} - 8t$
