Answer 1

Step-by-step explanation:

4x"2+9y"2+25z"2

plz mark

Answer 2

Answer:

Step-by-step explanation:

given :- ( 2x - 3y + 5z )²

by using identity ( a + b + c )² = a² + b² + c² + 2ab + 2bc + 2ac

here a = 2x, b = -3y and c = 5z

now let us solve it..

( 2x - 3y + 5z ) = (2x)² + (-3y)² + (5z)² + 2 (2x) (-3y) + 2 (-3y)(5z) + 2 (2x) (5z)

= 4x² + 9y² + 25z² - 12xy - 30yz + 20xz

HOPE THIS HELPS..!!
