M+n =7
mn =12
m3+m3
what is the value? ?​

Step-by-step explanation:

m+n = 7

m = 7 - n

mn = 12

(7 - n)n = 12 ( putting value of m )

7n - n² = 12

n² - 7n + 12 = 0

n² - 3n - 4n + 12 = 0

n ( n - 3 ) - 4 ( n - 3 ) = 0

( n - 4 ) ( n - 3 )

n = 4 , 3

m = 7 - n

m = 7 - 4 or 7 - 3

= 3 or 4

m3 + m3

3×3 + 3×3 or 4×3 + 4×3

9+9 or 12 +12

18 or 24

idk lol
