1) Calcule o resultado de
(a3 + 23a2 + 4a) + (2a3 - 17a2 + a)​

Answer 1

$\left(a\cdot \:3+23a\cdot \:2+4a\right)+\left(2a\cdot \:3-17a\cdot \:2+a\right)=26a\\\\\\\left(a\cdot \:3+23a\cdot \:2+4a\right)+\left(2a\cdot \:3-17a\cdot \:2+a\right)\\\\\\a\cdot \:3+23a\cdot \:2+4a+2a\cdot \:3-17a\cdot \:2+a\\\\\\8a+23\cdot \:2a+2\cdot \:3a-17\cdot \:2a\\\\\\8a+46a+2\cdot \:3a-17\cdot \:2a\\\\\\8a+46a+6a-17\cdot \:2a\\\\\\8a+46a+6a-34a\\\\\\26a$
