Tìm x biết: 8x(x – 2017) – 2x + 4034 = 0.
Giải thích
8x(x – 2017) – 2x + 4034 = 0
⇔ 8x(x – 2017) – 2(x – 2017) = 0
⇔ (x – 2017)(8x – 2) = 0
⇔ x−2017=08x−2=0
⇔ x=2017x=14
Vậy x = 2017 hoặc x = 14.
8x(x – 2017) – 2x + 4034 = 0
⇔ 8x(x – 2017) – 2(x – 2017) = 0
⇔ (x – 2017)(8x – 2) = 0
⇔ x−2017=08x−2=0
⇔ x=2017x=14
Vậy x = 2017 hoặc x = 14.
