數(shù)學(xué)考題練習(xí):分解因式:ax3y+axy3-2ax2y2=_

更新時(shí)間:2024-01-12 16:34:47作者:貝語(yǔ)網(wǎng)校

分解因式:ax3y+axy3-2ax2y2=________.

試題答案

axy(x-y)2

試題解析

先提取公因式axy,然后再利用完全平方公式繼續(xù)進(jìn)行因式分解.

解答:ax3y+axy3-2ax2y2,

=axy(x2+y2-2xy),

=axy(x-y)2

點(diǎn)評(píng):本題主要考查提公因式法分解因式和利用完全平方公式分解因式,熟記公式是解題的關(guān)鍵,難點(diǎn)在于進(jìn)行二次分解因式.
