Question

the following equaton has three solutions. look for the GCF then use the quadratic formula to find all solutions. 3x^3+1x^2+1x=0

Answer 1

x is the gcf
so, x (3x^2+x=1)=0
can you do it from here?

Answer 2

i factored out the x but now i dont know what to do with the quadratic formula

Answer 3

sorry, there was a typo

x (3x^2+x+1)=0

Answer 4

so i use the 3x^2+x+1 for the quadratic formula?

Answer 5

look, if x=0, then the equation is true. so that is one solution.
Yes then use the qudratic formula to find the other two solutions

Answer 6

will you be ok now?

Answer 7

i got \[(-1+\sqrt{11})/2\]

Answer 8

but its telling that not correct

Answer 9

hold on while i work it out

Answer 10

you did the sutbraction wrong under the rad

Answer 11

and it is -1+ or - the rad/2

Answer 12

still there?

Answer 13

yes i dont understand

Answer 14

-1 +-rad(1-4*3*1)/2*3
-1+-rad (-11)/6
