Find the value of alpha for which the co...

Find the value of `alpha` for which the coefficients of the middle terms in the expansions of `(1+alphax)^4a n d(1+alphax)^6` are equal, find `alphadot`

Text Solution

Verified by Experts

Coefficient of middle term in `(1 + αx)^4` = coefficient of middle term in `(1 – αx)^6 `
Therefore, `4_(C_2)α^2 = 6_(C_3)(– α)^3 `
`=> α = - 3/10`
