(x - y)³ = x³ - y³ - 3xy(x - y)

(-7)³ = x³ - y³ - 3(-10)(-7)

-343 = x³ - y³ -210

x³ - y³ = -133

The Brainliest Answer!

given x-y = -7 and xy = -10

but we know that

x²+y²=(x-y)² +2xy

= (-7)² +2(-10)

= 49-20

=29

substitute these in the above x³-y³ formula then we get

x³-y³ = (-7)(29-10)

= (-7)(19)

= -133
