Question

how many positive integers n are there which satisfy n^2-15n+14<0？

Answer 1

Answer:

13

Step-by-step explanation:

given

n²-15n+14<0

factorize

we get

(n-14)(n-1)<0

n<14. & n<1

here we neglect the second one

coz there is no positive integer less than 1

so n<14

there are 13 integers which satisfy the inequation
