Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).
However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).
In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
It will take 20 hours I think because 8,16,32,64 is the sequence of cars waxed and 3,6,12,24 are the hours, 64 take 4 away = 60. and then 24, I took 4 away from 64 so it would be 20 if I took away 4
You combine like terms
Example: 5x^3+3x+1-4x^3-2x-1
The answer would be x^3+x
7 because that’s just the right answer duhhhhhhh
