given f(x)=8x3 and g(x)=12x^5 , which of the following are true?
a) f(x)/g(x) = 2/3x^2
b) f(0) x g(1)=3
c) f(1)/g(1) =1
d) f(x) x g(x)=96x^15

a

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

step-by-step explanation:

55 degrees because 55+55=110 degrees
