Answer 1

Answer:

12 and 5

Step-by-step explanation:

n^2-5n-12n+60=0

n(n-5)-12(n-5)=0

(n-12)(n-5)=0

n=12 and n=5

Answer 2

To factorise :

• n² – 17n + 60 = 0

Solution :

n² – 17n + 60 = 0

[ S = –17 , P = 60 (–20, 3) ]

➠ n² + 3n – 20n + 60 = 0

➠ (n² + 3n) + (–20n + 60) = 0

➠ [ n(n + 3) ] + [ –20(n + 3) ] = 0

➠ (n + 3) (n – 20) = 0

∴ Required answer :

Factors are :

• n + 3 and n – 20

• n = –3
• n = 20
