Question

多項(xiàng)式x²-3x+2是

二

次

三

項(xiàng)式．

Answer 1

分析：解答此題，首先應(yīng)明白多項(xiàng)式的項(xiàng)數(shù)與次數(shù)的概念．多項(xiàng)式里次數(shù)最高項(xiàng)的次數(shù)，叫做這個(gè)多項(xiàng)式的次數(shù)，每個(gè)單項(xiàng)式叫做多項(xiàng)式的項(xiàng)．在多項(xiàng)式x²-3x+2中，次數(shù)最高的項(xiàng)是x²，此數(shù)為2，多項(xiàng)式共有3項(xiàng)．

解答：解：多項(xiàng)式x²-3x+2是（二）次（三）項(xiàng)式．
故答案為：二，三．

點(diǎn)評：此題考查了多項(xiàng)式中項(xiàng)數(shù)與次數(shù)的概念，明白其概念是解答的關(guān)鍵．
