Answer:
5
Step-by-step explanation:
1) N is equal to -6 and you are challenge to find the value in the expression n²+5n -1.
so we have:-
n= -6
the expression is n²+5n-1
2) next we substitute the value of n= -6 in the expression n²+5n-1. this means wherever we see 'n' in the expression, we replace it with '- 6 ' so instead of writing n we will write the value -6. thus we have:-
(-6)² + 5(-6) - 1
36+ (-30) - 1
36-30-1
