The value of the expression is -9 and the first step in simplifying this expression when n = -3 is (-3)^2
The expression is given as:
n^2 - 3(2) +4n
When n = -3, the expression becomes
(-3)^2 - 3(2) + 4(-3)
Evaluate the exponent and the product
9 - 6 - 12
Evaluate the difference
-9
Hence, the value of the expression is -9
The first step in simplifying this expression when n = -3 is to evaluate the bracket
Hence, the first step in simplifying this expression when n = -3 is (-3)^2
