X^4-256=0 numbers of rational roots

zhuklara [117]

Answer:

x = 8 or x = -8

Step-by-step explanation:

x^4 - 256 = 0

<=>x^4 - 4^4 = 0

<=>(x - 8)(x + 8)(x^2 + 64) = 0

Case 1 :

x - 8 = 0

<=>x = 8 (choose)

Case 2:

x + 8 = 0

<=>x = -8 (choose)

Case 3:

x^2 + 64 = 0

<=>x^2 = -64 (nonsense)

so x = 8 or x = -8

Done :))

The equation of a line is y-4=3(x+2) , which of the following is a point on the line? A (2, 4) B (4, -2) C (-2, 4) D (-4, 2)

liraira [26]

Answer:

Step-by-step explanation:

The point-slope equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

We have the equation

$y-4=3(x+2)\\\\y-4=3(x-(-2))$

Therefore

m = 3

(x₁, y₁) = (-2, 4)
