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.
X - an amount
To increase an amount by 3% you can multiply the amount by 1.03.
Answer:
80
Step-by-step explanation:
PEMDAS- do exponents first here, simplifying that to 64+16, add those to get 80.
