Question

求解二元一次方程！！！！ 简单的

6倍X的平方=（10-3x)-(8-2x)

Answer 1

6x²=10-3x-8+2x
6x²=2-x
6x²+x-2=0
(3x-2)(2x+1)=0
3x-2=0或2x+1=0
解得x=2/3或x=-1 /2

Answer 2

6x^2=(10-3x)-(8-2x)
6x^2=10-3x-8+2x
6x^2+x-2=0
(3x+2)(2x-1)=0
则3x+2=0
2x-1=0
则x=-2/3
x=1/2

Answer 3

6倍x的平方=（10-3x)-(8-2x)
6x^2=10-3x-8+2x
6x^2+x-2=0
(3x+2)(2x-1)=0
解得：x=-2/3或1/2

Answer 4

6x²=10-3x-8+2x
6x²+x-2=0
(2x-1)(3x+2)=0
x=1/2,x=-2/3

Answer 5

6x^2=10-3x-8+2x
6x^2+x-2=0
(3x+2)(2x-1)=0
x=-2/3，x=1/2

Answer 6

6x^2=2-x
(2X-1)(3X+2)=0
X1=1/2，X2=-2/3
