Explanation:
Given: (4x3)2
Use the binomial theorem for the second power, which we find that:
(a+b)2=a2+2ab+b2
(ab)2=a22ab+b2
Here a=4x, b=3, and we use the second formula.
So, we get:
(4x3)2=(4x)2234x+32
=16x224x+9

Explanation:
First let
a=4x
b=-3
we use the formula
a2+2ab+b2
so
(4x)2+2(4x)(3)+(3)2
the result will be
16x224x+9
