Question

(2x−y+5z)2−(3x−y)2 please solve this fast​

Answer 1

Answer:

well I'm giving two solutions pick yours ok?

if it's written (2x-y+5z)²-(3x-y)² then,

4x²+y²+25z²+4xy-10yz-20xz-9x²+6xy-y²

-5x²+25z²+10xy-10yz-20xz is the answer

OR if it's (2x−y+5z)2−(3x−y)2 then,

4x-2y+10z-6x-2y

-2x-4y+10z is the answer
