Given function $\"straight$ .

The coefficient of $\"x$ is 1,there 4, 2, 0 are pisitive real roots and 0 nagative real roots.

The possible rational zeros are $\"plus-minus$ .

$\"\"$

One zero is $\"\"$ 1.

$\"straight$

$\"x$ (Substitute f(x) = 0)

$\"x$

$\"open$ (Apply distributive property) $\"\"$

$\"\"$ (Set 1st factor on equal to zero)

$\"\"$ (Subtract 1 from each side)

$\"x$

$\"x$ (The imaginary value: $\"\"$ )

$\"\"$ (Set second factor on equal to zero)

$\"\"$ (Add 2 to each side)

$\"\"$ (Simplify)

$\"\"$ (Add)

Here another real zero at x = 2, two imaginary zeros at $\"\"$ . $\"\"$

The zeros of this function are $\"\"$ .
