N^2 + 5n - 1 evaluate the expression when n = - 6

5

Step-by-step explanation:

substitute n=-6 into the expression

therefore, (-6) ^2+5 (-6) - 1=36-30-1

=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
