Which function has a remainder of 3 when divided by x +2? Of(x) = x2+x+5
O Fix) = x2 + 3x +5
o fix)=x2-4x +7
Of(x)=x2-6x +11

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

the answer is  

a.

4,624π mm2

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
