(42:7) × 1 = 6 (quyển)

Loan có số vở là:

42 - 6 = 36 (quyển)

`|2/3x-2/5|-1/2=1-(-2/3)|`

`|2/3x-2/5|-1/2=5/3`

`|2/3x-2/5|=13/6`

`[(2/3x-2/5=13/6),(2/3x-2/5=-13/6):}`

`[(x=77/20),(x=-53/20):}`

\(\left(42:3\right)\times1=14\) (quyển)

a. PT có 2 nghiệm `x_1` và `x_2 <=> \Delta>=0`

`<=>5^2-4.1.(-3m)>=0`

`<=>m>=-25/12`

b. Không hiểu câu hỏi lắm ?

Số phần bằng nhau là:

`1+2=3` (phần)

Hồng có số quyển vở là:

Loan có số quyển vở là:

`(1/2 x-3)^2=(1/2x-3)^4`

`(1/2x-3)^2-(1/2x-3)^4=0`

`(1/2x-3)^2 [1-(1/2x-3)^2]=0`
