Question

guye please help me ​

Answer 1

Answer:

189

Step-by-step explanation:

x + y= 3 and xy = -18

so either x or y is a negative number

lets take x as the negative number

so y should be greater than x and the product of them both should be -18

so x will be -3 and y will be 6

-3+6=3 and -3*6=-18

$x^{3}+y^{3}=-3^{3} + 6^{3}$

= -27+216

= 189
