Question

計(jì)算：（6a²-2a）÷2a=________．

Answer 1

3a-1
分析：根據(jù)多項(xiàng)式除以單項(xiàng)式的法則計(jì)算即可．
解答：（6a²-2a）÷2a=
=6a²÷2a-2a÷2a
=3a-1．
故答案為3a-1．
點(diǎn)評(píng)：本題考查了多項(xiàng)式除以單項(xiàng)式的法則：多項(xiàng)式除以單項(xiàng)式，先把這個(gè)多項(xiàng)式的每一項(xiàng)分別除以單項(xiàng)式，再把所得的商相加．由法則可知，多項(xiàng)式除以單項(xiàng)式實(shí)質(zhì)就是轉(zhuǎn)化為單項(xiàng)式除以單項(xiàng)式．多項(xiàng)式除以單項(xiàng)式的結(jié)果仍是一個(gè)多項(xiàng)式．
