The correct Answer is:
To find the general term in the expansion of \((x^2 - y)^6\), we can use the binomial theorem. The binomial theorem states that: \[ (p + q)^n = \sum_{r=0}^{n} \binom{n}{r} p^{n-r} q^r \] For our case, we can identify \(p = x^2\), \(q = -y\), and \(n = 6\). ### Step 1: Identify the general term The general term in the expansion can be expressed as: \[ T_{r+1} = \binom{n}{r} p^{n-r} q^r \] Substituting our values: \[ T_{r+1} = \binom{6}{r} (x^2)^{6-r} (-y)^r \] ### Step 2: Simplify the general term Now, we simplify the expression: \[ T_{r+1} = \binom{6}{r} (x^2)^{6-r} (-y)^r = \binom{6}{r} x^{2(6-r)} (-y)^r \] This simplifies to: \[ T_{r+1} = \binom{6}{r} x^{12 - 2r} (-1)^r y^r \] ### Step 3: Final expression of the general term Thus, the general term \(T_{r+1}\) can be written as: \[ T_{r+1} = \binom{6}{r} (-1)^r x^{12 - 2r} y^r \] ### Conclusion The general term in the expansion of \((x^2 - y)^6\) is: \[ T_{r+1} = \binom{6}{r} (-1)^r x^{12 - 2r} y^r \]
