Question

計(jì)算：（9x⁴-15x²+6x）÷3x=

3x³-5x+2

．

Answer 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：解：（9x⁴-15x²+6x）÷3x=3x³-5x+2．
故答案為3x³-5x+2．

點(diǎn)評：本題考查了多項(xiàng)式除以單項(xiàng)式，先把這個多項(xiàng)式的每一項(xiàng)分別除以單項(xiàng)式，再把所得的商相加．注意：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)果仍是一個多項(xiàng)式．
