What is the factored form of x3 + x2 − 8x − 12 if (x + 2) is a factor?
we have the cubic function
x3 + x2 − 8x − 12
using a graphing tool
Find the zeros of the function
see the attached figure
please wait a minute
The zeros are -2 with multiplicity of 2 and 3
therefore
the factored form is equal to
(x+2)^2(x-3)
[tex](x+2)^2(x-3)[/tex]
