Question

solve for "N"


15n²- 88n + 119 = 0

Answer 1

hey mate....

$15 {n}^{2}-88n+119=0$

$15{n}^{2}-(105-17)n+119=0$

$15{n}^{2}-105n-17n+119=0$

$15n(n-7)-17 (n-7)$

$(n-7) (15n-17)$

15n-17=0

15n=17

n=17/15

n-7=0

n=7

Hope it's help uh..

Answer 2

15n²-88n-119=0

15n²-105n-17n-119=0

15n(n-7)-17(n-7)=0

(n-7)(15n-17)=0

hence, n=7,17/15
