What are the ROots:
ok the 13 really causes a problem because you can't factor that.
So I move the right side to the left and then you can't find a number that fits so that it equals zero so I tried factoring it somehow but can't do it can someone help?
A box has dimensions that are linear factors of (x^3-7x^2+14x-8) cubic centimetres. What dimensions give a volume of 12 cm cubed?
I started it off by moving 12 to the left side giving the equation:
then from then I don't know....If I substitute 5, the equation is...
