`x^2 - 5x + 6 = 0`
`<=> x^2 - 2x - 3x + 6 = 0`
`<=> x(x - 2) - 3(x - 2) = 0`
`<=> (x - 2)(x - 3) = 0`
`<=>` `x - 2 = 0` hoặc `x - 3 = 0`
`<=> x= 2` hoặc `x = 3`
Vậy `x = {2; 3}`

Giải:
`11` giờ kém `15` phút `=` `10` giờ `45` phút
Khoảng thời gian từ `9` giờ `25` phút đến `11` giờ kém `15` phút là:
`10` giờ `45` phút `-` `9` giờ `25` phút `=` `1` giờ `20` phút.

Ta có:
`x . a = aa`
`=> x = a`
`ab . x = abab`
`=>x = ab`
`abc . x = abcabc`
`=> x = abc`

`30%` của `20` là:
`20 . 30 : 100 = 600 : 100 = 6`
Đáp số: `6`
2024-03-04 20:48:28
2024-03-04 20:46:34
Số đó là:
`2746 : 35,9 . 100 = 7649,02507`
Đáp số: `7649,02507`
