Which will result in a difference of squares?
-7x+4)(-2x+2)
(-7x+4) 4-7x)
(-7x+4-7x-4)
(-7x+4)[7x-4)
Thd

Difference of squares= (a+b)(a-b) =a^2-b^2

(-7x+4)(-2x+2)= 14x^2-14x-8x+8 =
14x^2-22x+8 nope
(-7x+4)(4-7x)= -28x+49x^2+16-28x
=49x^2-56x+16 nope
(-7x+4-7x-4) that’s not even foiling so no
(-7x+4)(7x-4)= -49x^2+28x+28x-16
=-49x^2+56x-16

Did you type one of them in wrong cuz none of these end up equally difference of squares?

The first option would be correct if it were one half and not one
