CAN SOMEONE PLEASE PLEASE PLEASE HELP ME WITH THIS MATH PROBLEM, IT IS EASY I JUST DON'T UNDERSTAND IT. NO ONE IS HELPING ME PLEASE. ITS DUE IN LESS THAN A HOUR! SOMEONE HELP! f(x)= x^3 - 4x^2 - 3x + 12

Complete the problem by using the following steps to find the factored form of the polynomial.
1. Find all possible rational roots.
2. Use Descartes' rule of signs to determine the possible number of positive, negative, and
complex roots.
3. Use synthetic division and the quadratic formula to find all roots.
4. Write the polynomial in factored form.
Show ALL work for your steps.

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
