To find the zeroes of the polynomial function
, we need to solve the equation
.We can start by factoring the polynomial. Notice that
is a common factor in each term:
Now, we can set each factor equal to zero and solve for
:
To solve the quadratic equation
, we can use the quadratic formula:
In this case,
,
, and
. Plugging these values into the quadratic formula, we get:
\frac{-3 \pm \sqrt{9 - 8}}{2}
x = \frac{-3 \pm \sqrt{1}}{2}
x = \frac{-3 \pm 1}{2}
x = \frac{-3 + 1}{2} = -1
x = \frac{-3 - 1}{2} = -2
f(x) = x^3 + 3x^2 + 2x
0
-1
-2$.
