Use Pascal's Triangle to complete the expansion of (s + t)^3. s^3 + ____s^2t + 3st^2 + t^3

Pascal's Triangle Coefficients: Pascal's Triangle for the third row is 1, 3, 3, 1. These numbers are the coefficients for the expansion.Second Term Coefficient: The second term in the expansion will have the coefficient 3 from Pascal's Triangle, so it's 3s^2t.Full Expansion: Now, write down the full expansion using the coefficients: s^3 + 3s^2t + 3st^2 + t^3.

\newline

s^3 +

____

s^2t + 3st^2 + t^3

Pascal's Triangle Coefficients: Pascal's Triangle for the third row is $1, 3, 3, 1$ . These numbers are the coefficients for the expansion.
Second Term Coefficient: The second term in the expansion will have the coefficient $3$ from Pascal's Triangle, so it's $3s^2t$ .
Full Expansion: Now, write down the full expansion using the coefficients: $s^3 + 3s^2t + 3st^2 + t^3$ .
