To state : The given statement is always true, sometimes true or never true.
The given statement is sometimes true.
Given information :
The statement is "A polynomial function with real coefficients has real zeros."
Explanation :
Check the given statement with help of an example.
Take a function
Make graph of the function.
The graph intersects the
Use synthetic division.
So,
Solve
Here,
So,
The zeros of the given function are
Therefore, it has two real and two complex roots.
Hence, the given statement is sometimes true not always.
