1 - 4x^2 Factorization using the formula: a^2 - b^2 = (a + b) (a - b)

is the answer: (1 + 2x) (1 - 2x)

is it in the right order though?

    Yes

    Step-by-step explanation:

    Factorise using the difference of squares, that is

    a² - b² = (a + b) (a - b)

    Given

    1 - 4x², then a = 1 and b = 2x

    = (1 + 2x) (1 - 2x) = (1 - 2x) (1 + 2x)

    Since multiplication is commutative order is not important, that is

    3 * 4 = 4 * 3

    1 - 4x^2

    = (1) ^2 - (2x) ^2

    = (1-2x) (1+2x)

    it could also be written as (1 + 2x) (1 - 2x)

    Step-by-step explanation:

    the order doesn't matter because it's a multiplication
