    \[\left( -15p^4+\frac{ 21 }{ 2} p^3-\frac{ 45 }{ 2 }p^2+63p-36\right) \left( 9p-9 \right)\]

    right now right the coefficients|dw:1443658432075:dw| carry down the leading coefficient then multiply by 1 write the answer above the line and then combine them

    so it's \[\frac{ 21 }{ 2}-15\] -15 is same as -15/1 \[\frac{ 21 }{ 2}-\frac{15}{1}\]find the common denominator

    wait do you mean 3 is a common denominator ?

    when the denominator are not the same we should multiply them

    no common denominator is 2 like i said when the common denominator aren't the same we should multiply them 2 times 1 = 2 \[\frac{\color{ReD}{ 1}(21)-\color{blue}{2}(15) }{ 2}\] and when we write it as common denominator we should multiply the numerator of first fraction with the denominator of 2nd fraction and multiply the numerator of 2nd fraction by the denominator of 1sst one

    |dw:1443660350489:dw|\[-\frac{ 45 }{ 2 }-\frac{ 9 }{ 2}\]this one would be easy denominators are the same

    \[-15p^4-\frac{ 9 }{ 2 }p^3+18p^2+81p+45\] this is my final answer @Nnesha
