资源描述

1因式分解法解一元二次方程配套练习 1、 用因式分解法解方程 5(x+ 3)-2x(x +3)=0,可把其化为两个一元一次方程 -_和_求解。2、如果方程 x2-3x+c=0 有一个根为 1,那么 c=_,该方程的另一根为_, 该方程可化为(x -1) (x_)=03、用因式分解法 解下列方 程:(1)x 25x 0 (2)(3x+2) 2-4x2=0;(3)(x+2) 2=3x+6; (4) (2x-1) 2=(3-x) 2 (5) (2x3) (3x1)650【挑战】4已知关于 x的方程 22()(4)30axax。(1)当 为何值时,方程有一根为 0?并求出这时方程的另一个根。(2)当 为何值时,方程的两根互为相反数?并求出这 时方程的解。【循环练】5、解方程: 21()90x
