You can put this solution on YOUR website! Find all zeros of the polynomial functions. Show the process.
2x^3 + 5x^2 - 4x - 3
------
Note:: Since the coefficients add up to zero, x = 1 is a zero.
-------
1)....2....5....-4....-3
......2....7....3...}.. 0
---------
Quotient:: 2x^2 + 7x +3
Facor::
(2x+1)(x+3)
-------
Other zeroes:: x = -1/2 ; x = -3
------------
Answer: x = 1 OR x = -1/2 ; OR x = 3
====================
