Factor the following polynomial completely. -x^2y^2 + x4 + 4y^2 - 4x^2 1.) (x - 2)(x - 2)(x + y)(x - y) 2.) (x + 2)(x + 2)(x + y)(x - y) 3.) (x + 2)(x - 2)(x + y)(x - y)

-x^2y^2 + x4 + 4y^2 - 4x^2

= x^2(x^2 - y^2) -4(x^2 - y^2)

= (x^2 - y^2) (x^2 - 4)

=(x + y)(x -y)(x + 2)(x - 2)

answer

3.) (x + 2)(x - 2)(x + y)(x - y)

= (y^2 - x^2) (

step-by-step explanation:

use that smart brain

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
