If $a - b = 6$ , then find the value of $a^{3} - b^{3} - 18 a b$

a = 6 p

b = 3 p

(a + b)^{2} + (a - b)^{2}

\int \frac{3 e^{x} - 5 e^{- x}}{4 e^{x} + 5 e^{- x}} d x = a x + b ln (4 e^{x} + 5 e^{- x}) + c

By how much is $5 a^{2} b^{2} - 18 a b^{2} - 10 a^{2} b$ greater than $- 5 a^{2} + 6 a^{2} b - 7 a b$ ?

A = \sqrt{6}

B = \sqrt{18}
