Solution for question 1


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = 2x and b = y
((2x)3 - y3) = (2 x - y)((2x)2 + (2 x)(y) + y2)
                    = (2 x - y)((22x2) + 2 x y + y2
                    = (2 x - y)(4 x2) + 2 x y + y2

Solution for question 2


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = x and b = 3 y
((x)3 - (3y)3) = (x - 3y)((x)2 + (x)(3y) + (3y)2)
                    = (x - 3y)(x2 + 3 x y + (32y2)
                    = (x - 3y)(x2 + 3 x y + 9y2)

Solution for question 3


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = 3x and b = y
((3x)3 - (y)3) = (3 x - y)((3 x)2 + (3 x)(y) + (y)2)
                    = (x - 3y)(x2 + 3 x y + 9 y2)

Solution for question 4


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = 2 S and b = T
((2S)3 - (T)3) = (2 S - T)((2S )2 + (2 S)(T) + (T)2)
                    = (2 S - T)(4S )2 + 2 S T + T2)

Solution for question 5


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = 3 N and b = 2 L
((3 N)3 - (2 L)3) = (3 N - 2 L)((3 N )2 + (3 N)(2 L) + (2 L)2)
                    = (3 N - 2 L)(9 N2 + 6 N L + 4 L2)

Solution for question 6


jQuery UI Accordion - Default functionality
(a3 - b3) = (a - b)(a2 + a b + b2)
here a = P and b = Q
(P)3 - (Q)3 = (P - Q)((P )2 + P Q + (Q)2)
