Find all the zeroes of the polynomial function f(x)=x^3-5x^2+6x-30 using synthetic division.
WITCHER [35]
Write the coeeficientes of the polynomial in order:

  | 1   - 5   6   - 30
  |
  |
  |
------------------------

After some trials you probe with 5

   | 1   - 5       6     - 30
   |
   |
5 |        5      0       30
-----------------------------
     1     0      6        0 <---- residue

Given that the residue is 0, 5 is a root.

The quotient is x^2 + 6 = 0, which does not have a real root.

Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.

What are the coordinates of the point (10, -4) if it is reflected across the y- axis?
iVinArrow [24]

Answer:

(-10,-4)

Step-by-step explanation:

The point is moved to the other side of the y axis.

The y coordinate would stay the same and the x coordinate would move the same number of units but on the opposite side (that's why its -10).
