I think you have to multiply across.
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".

Step-by-step explanation:
4x + 8y = 24 because you have 4 inches for ever x and 8 inches for every y and 24 inches is the same thing as 2 feet
Sped 2.4 mile sin 10 minutes. THat means in 1 hour 2.4 x6=14.4 miles per hour. 1 hour=60 minutes.
