Binomial Expansion
Largest term in the expansion
Steps:
- First of all, locate n or r which is given(known).
- Use the formula, nCr x a^(n-r) x b^r. Replacing known variable with their values.
- Press "CALC" in calculator and examine value of r which gives the value maximum.
- after finding r (r+1)th term will be largest term, and putting value of r in the expansion, You will get largest term.
