Answer: tbh all u have to do is multiply the numbers with the matching variable and see if it matches on the other side. 16x²−64y²=(4x−8y)(4x+8y)

x²-169=(x-13)(x+13)

9x²-1=(3x-1)(3x+1)

those are the true statements

bc 3•3 is 9, 13•13 is 169, and 4•4=16, 8•8=64

Edit: sorry if that came out rude I didn't mean for it to
