B. f(x)=7 x2 +10 and g(x) =
X-10
7
C. f(x) = {x+2-7 and g(x) = (x+2)° +7
3x+8
D. f(x)=
and g(x) = (7x-8)
7

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

the bolded word " farsighted" could be replaced with visionary.

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
