因式分解解方程:-8x^2+10x=0,4x^2=(3x-1)^2

因式分解解方程:-8x^2+10x=0,4x^2=(3x-1)^2
因式分解解方程:-8x^2+10x=0,4x^2=(3x-1)^2

因式分解解方程:-8x^2+10x=0,4x^2=(3x-1)^2
8x^2-10x=0
2x(4x-5)=0
所以x1=0,x2=5/4.
4x^2-(3x-1)^2=0
(2x)^2-(3x-1)^2=0
(2x-3x+1)(2x+3x-1)=0
(-x+1)(5x-1)=0
(x-1)(5x-1)=0
所以:
x1=1,x2=1/5.

因式分解解方程:
(1) -8x^2+10x=0
解,得:
8x^2-10x==0
4x^2-5x==0
x(4x-5)==0
x1==5/4,
x2==0
(2)4x^2=(3x-1)^2
解,得:
(2x)^2-(3x-1)^2=0
(2x-3x+1)(2x+3x-1)=0
(x-1)(5x-1)=0
所以:x
1=1,
x2=1/5
