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 expressions would be 0.25a
