MHB Find all possible solutions of c and d
(d+c)(d-c)=8621=(8621)(1)=(233)(37) the solution is (d,c)=(4311,4310),(135,98)# sorry again I have a poor calculation we have two sets of solution d=135 or 4311 c=98 or 4310 (d,c)=(4311,4310),(135,98)#- albert391212

MHB What is the Value of N in the Equation N + S(N) = 2000?
Let N=abcd , and S(N)=a+b+c+d<28 ,we have a=1, b=9 N+S(N)=1000+900+10c+d+1+9+c+d=1910+11c+2d=2000 11c+2d=90 we get c=8 , d=1 so N=1981 #- albert391212

MHB Find the solution of f(x)=x^3+4x- 6=0
sorry I mistype the function in my program I tried again using the correct function and put seed 1 , and get the answer x=1.1347 there is only one solution x=1.1347- albert391212

MHB Find the solution of f(x)=x^3+4x- 6=0
Please find the solution of polynomial function : $$f(x)=x^3+4x- 6=0$$ I use Newton's method to solve it and I also write a program (using excel) for help$$$$$$$$- albert391212

N + S(N) = 2000 N is a 4-digit number,and S(N) is the sum of each digit of N given N+S(N)=2000 please find N- albert391212
