Factor completely

A2 - b 2=(a + b) ( a - b) where a =2 and b =x2.

              2(2 + x2) ( 2 - x2)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula,

i dont know

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
