Finding the constant term of Arithmetic Expression Let us study the concept by finding the constant term in the expansion of (x3 – 1/x2)15 In (a + b)n the (r + 1)th term Tr+1 is given by –Tr+1 = nCr .an-r. br for r = 0, 1, 2, 3, 4, 5 … n Let constant terms occurs at (r+1)th term for ( x3 – […] Read More →
