A polynomial P has zeros when x=0, x=-1/6 and x=-3 Whats could be the equation p?
erma4kov [3.2K]

Answer:

P(x) = x^{3} + \frac{19}{6} x^{2} + \frac{1}{2} x

Step-by-step explanation:

x(x + 1/6)(x + 3) = P

x(x^{2} + 3x + 1/6(x) + 1/2) = P

x (x^{2} + 19/6(x) + 1/2) = P

x^{3} + \frac{19}{6} x^{2} + \frac{1}{2} x = P(x)

How do you solve this
AlladinOne [14]

Answer:

  • domain: all terms are defined for <em>all real numbers</em>
  • solution: x = 6

Step-by-step explanation:

Rewrite the equation as a single exponential. After taking the log, the solution becomes obvious.

5^{x-2}-7^{x-3}=7^{x-5}+11\cdot 5^{x-4}\\\\5^{x-2}-11\cdot 5^{x-4}=7^{x-3}+7^{x-5}\\\\5^{x-2}(1-11\cdot 5^{-2})=7^{x-3}(1+7^{-2})\\\\5^{x-2}\dfrac{14}{25}=7^{x-3}\dfrac{50}{49}\\\\1=\dfrac{2\cdot 7^{x-3}5^4}{2\cdot 5^{x-2}7^3}=\left(\dfrac{7}{5}\right)^{x-6}\\\\0=(x-6)\log(1.4)\\\\x=6
