X^4-3x^2+2=0<br> Đặt ẩn t

AfilCa [17]

Answer:

$x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2}$

Step-by-step explanation:

x⁴ - 3x² + 2 = 0

x^2×2 - 3x² + 2 = 0

(x²)² - 3x² + 2 = 0

t² - 3t + 2 = 0

t = 1, t = 2

x² = 1, x² = 2

x = -1, x = 1

x = - square root 2, x = square root 2

$x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2}$

6x-2=8x-8 please i forgot how you do this

AlladinOne [14]

Answer:

x = 3

Step-by-step explanation:

6x - 2 = 8x - 8 ( subtract 8x from both sides )

- 2x - 2 = - 8 ( add 2 to both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3

Find the slope of the line that passes through each pair of points

AnnZ [28]

Use the slope formula: $\frac{y2-y1}{x2-x1}$

1. (4, 9), (1, -6)

$\frac{-6-9}{1-4} = \frac{-15}{-3} = 5$

2. (2, 5), (6, 2)

$\frac{2-5}{6-2} = \frac{-3}{4}$

3. (4, 3.5), (-4, 3.5)

$\frac{3.5-3.5}{-4-4} = \frac{0}{-8} =0$

4. (1, -2), (-2, -5)

$\frac{-5-(-2)}{-2-1} =\frac{-3}{-3} = 1$
