Question

【題目】多項(xiàng)式x2﹣3x+2是　 　次　 　項(xiàng)式．

Answer 1

【答案】二，三

【解析】

試題分析：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：多項(xiàng)式x2﹣3x+2是（二）次（三）項(xiàng)式．

故答案為：二，三．
