Question

(N-1)*(n+2)=180 find n

Answer 1

Answer:

n=13 or n=-14

Step-by-step explanation:

is the 'n' in the first bracket different from the 'n' in the second bracket? since it is is in uppercase.

if bot are the same then here's your answer,

(n-1)(n+2)=180

n^2+2n-n-2=180

n^2+n-182=0

n^2+14n-13n-182=0

n(n+14)-13(n+14)=0

(n-13)(n+14)=0

n=13 or n=-14
