Algebra.Com's Answer #644770 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! The coefficients of a binomial expansion such as this can be found using Pascal's Triangle: \n" ); document.write( "1 \n" ); document.write( "11 \n" ); document.write( "121 \n" ); document.write( "1331 \n" ); document.write( "14641 \n" ); document.write( "Here is the group for n=4 power... \n" ); document.write( "Now when you expand a binomial, the powers of the first term go from four to zero, and the powers of the second term go from zero to four...so that \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So the coefficient of the x^2 term is 24. \n" ); document.write( " |
