Ah, binomial expansion? It is about finding the term where the power of x becomes zero. You use the general term formula, T_{r+1} = nCr * a^{n-r} * (b)^r, and set the exponent of x to zero to solve for r. But in my life, the only ‘independent term’ I look for is whether my cousin’s apple trees will hold their fruit before the hailstorm comes—the calculations in my maths notebook feel less urgent than the ones in the orchard ledger.
