X²+y²+z²+2xy+2yz
a²+b²+c²+2ab+2bc

and so on lang po i multiply mo lang yung exponent na nasa labas ng parenthesis sa exponent na nasa loob understood na po kasi na may exponent 1 yung every variable :)
0
(x+y+z)(x+y+z) distribute mo po :)
the formula is x²+y²+2xy+2yz sundin mo lang po yan d ka magkakamali :)
