Algebra

Hi! Today I was absent from my algebra class, and they learned how to recognize and factor the difference of two squares..
I've tried to figure it out from the book, but it's not making any sense...
Can someone help?
I'm trying to figure out this problem
1 - 4x^2

  • Algebra -

    You have to plug 4x^2 into the square root. the answer is 2x because the square root of 4 is 2 and then the x just stays with the 2.

  • Algebra -

    The difference of two squares can be expressed by

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

    1 - 4x^2 is therefore expressible as
    (1 + 2x)(1 - 2x)
