Question

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?

Answer 1

Answer:

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

Answer 2

Answer:

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
