WebLet (2x +3)3 be a given binomial. From the binomial expression, write down the general term. Let this term be the r+1 th term. Now simplify this general term. If this general term is a constant term, then it should not contain the variable x. Let us write the general term of the above binomial. T r+1 = 3Cr (2x)3−r 3r. WebThe power that we are expanding the bracket to is 3, so we look at the third line of Pascal’s triangle, which is 1 3 3 1. So the answer is: 3 3 + 3 × (3 2 × x) + 3 × (x 2 × 3) + x 3 (we are replacing a by 3 and b by x in the expansion of (a + b) 3 above) WebJan 15, 2024 · Let (r + 1) th term be independent of in the given expression . Now T r + 1 = 10 Cr (3x) 10 – r ( – \(\frac{1}{2x^3}\)) r = 10 Cr (3x) 10 – r ( – \(\frac{1}{2}\)) r x 30 − 6. This term is independent of x, if . 30 – 6r = 0 . ⇒ r = 5 . So, (5 + … the psijics calling quest
