(2x+3)^3 = 3C3*(2x)^3 + 3C2*(2x)^2*3 + 3C1(2x)*3^2 + 3C0*3^3 \n" ); document.write( "---------------------------------------------------------------------- \n" ); document.write( "2. (2x-y)^6 \n" ); document.write( "Same pattern as above but starting with 6C6 \n" ); document.write( "----------------------------------------------- \n" ); document.write( "3. What is the 3rd term of the expansion for (x+3)^7 \n" ); document.write( "Ans: 7C5(x^5)(3^2) \n" ); document.write( "------------------------------- \n" ); document.write( "4. What is the 5th term of the expansion for (2x-3y)^5 \n" ); document.write( "Ans: 5C1(2x)(-3y)^4 \n" ); document.write( "------------------------------------- \n" ); document.write( "5. find the coefficient of x3 in the expansion (x+3)^5 \n" ); document.write( "Ans: 5C3(x^3)*3^2 \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
