Question

anybody pls expand this pls ​

Answer 1

Explanation:

Here we use property =(X+Y+Z) ^2=

X^2 +y^2 +z^2 +2xy+2yz+2zx

Here,x=(4x)^2

Y=(3Y) ^2

Z=(2)^2

But here in - 24xy and - 12y in this case is one minus sign and in both y is common therfore our y is negative. Then our expandation is=

(4x)^2 +(-3y)^2 +(2)^2 +2×4x×(-3y)+2×(-3y) ×2+2×2×4x
