Find all values of x such that 9+27x+8x2=0.If you find more than one value, then list your solutions, separated by commas.
9+27x+8x2=0
answer: -1/3, -8/3
Multiply both sides by x^2
and you will get 9x2+27x+8=0
which is equal to (3x+1)(3x+8)=0
set 3x+1 = 0 and solve for x.
you will get -1/3
set 3x+8=0 and solve for x
you will get -8/3
