Bài 10:

a) (x+2)² -x(x+3) + 5x = -20

=> x² + 4x + 4 - x² - 3x + 5x = -20

=> 6x = -20 + (-4)

=> 6x = -24

=> x = -4

b) 5x³-10x²+5x=0   

=>5x(x²-2x+1)=0

=>5x(x-1)² =0

=> 5x=0 hoặc (x-1)²=0

=>x=0 hoặc x=1

c) (x² - 1)³ - (x⁴ + x² + 1)(x² - 1) = 0

=> (x² - 1)[(x² - 1)² -  (x⁴ + x² + 1)] = 0

<=> (x² - 1)(x⁴ - 2x² + 1 - x⁴ - x² - 1) = 0

<=>  (x² - 1)(-3x²) = 0

<=> (x² - 1)=0 hoặc (-3x²) =0

<=> x²=1 hoặc x²=0

<=> x=−1;1 hoặc x=0

d)

⇔x=-23/12

Gọi chiều rộng khu vườn đó là : a ( a > 0 ) ( m )

Do chiều dài gấp 2 lần chiều rộng nên chiều dài là 2a ( m )

Do nếu tăng chiều rộng thêm 4 m và giảm chiều dài 6 m thì diện tích không đổi .

Ta có phương trình :

a×2a=(a+4)(2a−6)

⇔2a²=2a²−6a+8a−24

⇔−2a=−24

⇔a=12(tm)

Vậy chiều rộng khu vườn là 12 m

Chiều dài khu vườn là 24 m
