Answer:
0
Step-by-step explanation:
The remainder theorem says when you are dividing P(x) by (x-c), then the remainder is P(c).
So we need to evaluate x^2+2x-15 for x=3.
3^2+2(3)-15
9+6-15
15-15
0
So the remainder is 0.
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".
