I need it again.
Evaluate c^{3} -2b+a when c= 3,b= -5, and a= - 12.

SOLUTION pls.


Sagot :

[tex]c = 3 \\ \: \: \: b = - 5 \\ \: \: \: \: \: a = - 12[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: {c}^{3} - 2b + a = 3^{3} - 2( - 5) + ( - 12) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 27 + 10 - 12 \\ = 25 \\ [/tex]
