PLS ANS THIS AND GET 15 POINTS ..

IF x+y=8,x_y=4,xy=12,Then the value of x^3+y^3=??​

Answer 1

Answer:

224

Step-by-step explanation:

x+y=8 ....... (1)

x-y=4 ........ (2)

by elimination we get,

2x=12

x=6,

put this value in 1,we get

y=2.

also, xy=12( we are getting this value so the values are correct)

therefore,x^3+y^3= 216+8=224
