write the binomial expansion for question # 1 & 2?
\n" ); document.write( "1. (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( "==========================
