WebJan 12, 2024 · The basis of the induction is n = 0, which you can verify directly is true. Now assume it is true for some value of n. Now if (1+x) is nonnegative, you can multiply both sides by (1+x) to get the left side in the correct form. Expand the right-hand side, and rearrange it into the form (1+x)^ (n+1) >= 1 + (n+1)*x + n*x^2. WebThus, holds for n = k + 1, and the proof of the induction step is complete.
