Question

(x+5)²-(x+3)²=(x-1)²-(x-3)²

Answer 1

$( x+5)^{2} -( x+3)^{2}=( x-1)^{2}-( x-3)^{2} \\ x^{2} +10x+25- x^{2} -6x-9= x^{2} -2x+1- x^{2} +6x-9 \\ 4x+16=4x-8 \\ Fals$

Answer 2

rezulta
x²+10x+25-(x²+6x+9=x²-2x+1-(x²-6x+9)
x²+10x+25-x²-6x-9=x²-2x+1-x²+6x-9
4x+16=4x-8
4x-4x=-8-16
0=--24   fals
