Given that 2ab-b = 5, ab = 3 / 2, find the quadratic power of 4A + the quadratic power of B-1

Given that 2ab-b = 5, ab = 3 / 2, find the quadratic power of 4A + the quadratic power of B-1


b=5-2ab=5-3=2,2a=3/2,4a=2*2a=3,
(4a)^2+b^2-1=3^2+2^2-1=12



Ab ˇ - 4AB + 4A ˇ is quadratic


Original formula = a (B & # 178; - 4B + 4a)



Calculation: - 2 × (n power of a) × {3 × (n + 1 power of a) + 4a-1)}


The ambiguity of {3 × (n + 1 power of a) + 4a-1)},
1: Multiply before add
-2a^n*[3a^(n+1)+4a-1]
=-6a^(2a+1)-8a^(n+1)+2a^n
2: Add before multiply
-2a^n*{3[a^(n+1)+4a-1]}
=-6a^(2a+1)-24a^(n+1)+6a^n
