Question

If a+b=10 and ab=12, find the value of a^3+b^3

Answer 1

Answer:

a³ + b³ + 3ab(a+b)= (a+b)³

a³ + b³ + 3*12*10 = (10)³

a³ + b³ + 360 = 1000

a³ + b³ = 1000 - 360 = 640

Answer 2

Answer:

Given,a+b = 10

ab=12

to find,

a³+b³

a=12/b

12/b+b=10

12+b²=10b

b²+10b+12=0

question is wrong!!!!!
