Let's simplify step-by-step.
(2x+3y−4z)2+(2x−3y−4z)2
Distribute:
=4x2+12xy+−16xz+9y2+−24yz+16z2+4x2+−12xy+−16xz+9y2+24yz+16z2
Combine Like Terms:
=4x2+12xy+−16xz+9y2+−24yz+16z2+4x2+−12xy+−16xz+9y2+24yz+16z2
=(4x2+4x2)+(12xy+−12xy)+(−16xz+−16xz)+(9y2+9y2)+(−24yz+24yz)+(16z2+16z2)
=8x2+−32xz+18y2+32z2
Answer:
=8x2−32xz+18y2+32z2
