Perform the indicated operations. $$
\left( 19 t ^ { 4 } - 2 t ^ { 2 } + 4 t \right) + \left( 2 t ^ { 4 } - 4 t + 27 \right) - \left( 4 t ^ { 4 } + t ^ { 2 } + 19 \right)
$$
A) $16 t ^ { 4 } + 8$
B) $17 t ^ { 4 } - 3 t ^ { 2 } + 8$
C) $21 t ^ { 4 } - 3 t ^ { 2 } + 8 t - 8$
D) $25 t ^ { 4 } - 3 t ^ { 2 } + 46$

Quizplus · Accepted Answer

Combine like terms: $ (19t^4 + 2t^4 - 4t^4) + (-2t^2 - t^2) + (4t - 4t) + (27 - 19) = 17t^4 - 3t^2 + 8 $.

Perform the Indicated Operations (19t4−2t2+4t)+(2t4−4t+27)−(4t4+t2+19)\left( 19 t ^ { 4 } - 2 t ^ { 2 } + 4 t \right) + \left( 2 t ^ { 4 } - 4 t + 27 \right) - \left( 4 t ^ { 4 } + t ^ { 2 } + 19 \right)(19t4−2t2+4t)+(2t4−4t+27)−(4t4+t2+19)

Perform the Indicated Operations $\left( 19 t ^ { 4 } - 2 t ^ { 2 } + 4 t \right) + \left( 2 t ^ { 4 } - 4 t + 27 \right) - \left( 4 t ^ { 4 } + t ^ { 2 } + 19 \right)$
