(7a + 4b ) [ (7a)²-2(7a)(4b)+(4b)²]
= (7a+4b) [ (7a-4b)²]
= (7a +4b) (7a-4b) (7a-4b)
(a+b(a-b) = a²-b²
= (49a²-16b²)(7a-4b)
= 49a²(7a-4b)-16b²(7a-4b)
= 343a³-196a²b - 112b²a + 24b³
= (7a+4b) [ (7a-4b)²]
= (7a +4b) (7a-4b) (7a-4b)
(a+b(a-b) = a²-b²
= (49a²-16b²)(7a-4b)
= 49a²(7a-4b)-16b²(7a-4b)
= 343a³-196a²b - 112b²a + 24b³
