Question

Evaluate expression when n=3 n2 - 5n+2

Answer 1

the first step to solving this is to put the 3 in where n is.
(3)² - 5(3) + 2
now we start to solve by evaluating the power
9 - 5 x 3 + 2
next youll multiply -5 by 3
9 - 15 + 2
use both addition and subtraction rules to calculate the expression.
-4
this means that the correct answer to your question is -4.
