Hello from MrBillDoesMath!
Answer: 6 u^2 + 4u + 6 = 0 where u = (x-5)^2
Discussion; I think the problem statement should actually be to rewrite <u>this</u> equation:
6 (x-5)^4 + 4 (x-5)^2 + 6 -= 0.
Note the power of "x-5" is 4 in the first term and is 2 in the second term. That is, the power of x-5 in the first terms is double, or the square, of the (x-5) power occurring in the second term. This suggest the substitution u = (x-5)^2. Then the equation can be rewritten as
6 u^2 + 4u + 6 = 0
which is a quadratic in "u".

Answer:
The present worth of the money is important to understand before dwelling into the true discount. Any money that is to be paid before the due date is cleared off for debt is known as the present worth of the money.
True discount can be understood in reference to this present worth. The difference between the present worth of the money and the amount is known as the true discount.
Also, it can be stated as the interest in any present worth for the amount of time the debt is due to be discharged
