Use Pascal's triangle and the pattern of decreasing powers of a and increasing powers of b to expand (3x + 2Y)^5. I am unsure of how they want me to use Pascal's triangle with the coefficents.

    I dont understand how to get the coefficents of the expanded form using just pascal's triangle

    Now do you know that they are the "combinations"

    I can get each one using the general term formula but it says to use pascal's triangle

    yes I know that The coefficent is the number of ways for that spefic combination

    See each line gives you all the coefficients of the nCn for their respective number of terms

    yea now how do i change that with the coefficents infront of the variable without using the general term formula

    okay so just add the descending and ascending a and b values to the row of pascal's triangle?
