( 2x - 16 )( 12 - 6x ) = 0
TH1:
2x - 16 = 0
2x = 0 + 16
2x = 16
x = 16 : 2
x = 8
TH2:
12 - 6x = 0
6x = 12 - 0
6x = 12
x = 12 : 6
x = 2
=> x \(\in\){ 2;8 }
(2x - 16)(12 - 6x) = 0
=> 2x - 16 = 0 => x = 8
hoặc 12 - 6x = 0 => x = 2
Tìm x :
(2x-16)(12-6x)=0
2x-16 =0
2x =0+16
2x =16
x =16:2
x =8
Hoặc:12-6x=0
6x=0+12
6x=12
x=12:6
x=2
Vậy:x=8 hoặc x=2
2x - 16 = 0 hay 12 - 6x = 0
2x = 0 + 16 hay 6x = 12 - 0
2x = 16 hay 6x = 12
x = 16 : 2 hay x = 12 : 6
x = 8 hay x = 2
Nhớ k cho mk nha!!!
