Question

Find all solutions to the equation 6x^3+30x^2+45x+27=0

Answer 1

Answer:Option #1

Explanation:



Answer 2

all zeroes are

x = -3, {-2+(square root of 22)}/ 2

or {-2-(square root of 22)}/ 2

Explanation:

6x^3+30x^2+45x+27= 0

divide both sides with 3

2x^3+10x^2+15x+9=0

(x+2)(2x^2+4x+3)=0

let 2x^2+4x+3 =0

then x= {-2+(square root of 22)}/ 2

or x = {-2-(square root of 22)}/ 2

similarly if x+3=0

then x = -3
