數(shù)學(xué)考題練習(xí):解下列方程:x(x-3)-2x+6=0.

更新時(shí)間:2024-01-12 16:43:17作者:貝語網(wǎng)校

解下列方程:x(x-3)-2x+6=0.

試題答案

解:x(x-3)-2x+6=0,

∴x(x-3)-2(x-3)=0,

分解因式得:(x-3)(x-2)=0,

∴x-3=0,x-2=0,

∴x1=3,x2=2.

試題解析

分解因式得出(x-3)(x-2)=0,推出x-3=0,x-2=0,求出方程的解即可.

點(diǎn)評(píng):本題考查了對(duì)解一元一次方程和解一元二次方程的應(yīng)用,關(guān)鍵是把一元二次方程轉(zhuǎn)化成一元一次方程,題目比較典型,難度不大.
