Answer (4)

( 3 z + 2 k ) 2 = ( 3 z ) 2 + 2 ⋅ 3 z ⋅ 2 k + ( 2 k ) 2 = 9 z 2 + 12 k z + 4 k 2

You can solve this by the 1st identity which is (a+b)=a^2+b^2+2ab (3z)^2+(2k)^2+2 3z 2k =9z^2+4k^2+12kz

To solve ( 3 z + 2 k ) 2 , use the binomial expansion formula to get 9 z 2 + 12 z k + 4 k 2 . This involves squaring each term and adding them together, including the cross term. The final expanded form is 9 z 2 + 12 z k + 4 k 2 .
