Answer:
[tex]-12[/tex]
Step-by-step explanation:
We have been given an expression [tex]-4b-8+(-1b)^2+2b^3[/tex]. We are asked to evaluate our given expression at [tex]b=-2[/tex].
To evaluate our given expression, we will substitute [tex]b=-2[/tex] in given expression.
[tex]-4(-2)-8+(-1*-2)^2+2(-2)^3[/tex]
[tex]8-8+2^2+2(-8)[/tex]
[tex]0+4-16[/tex]
[tex]-12[/tex]
Therefore, the value of our given expression is [tex]-12[/tex].
