Question

(x +y)(x² – xy + y²) is equal to ……..
a)(x + y)³
b)(x – y)³
c)x³ + y³
d)x³ – y³​

Answer 1

Answer:

c)x^3 + y^3

Step-by-step explanation:

It is a formula of polynomials.

(x+y)(x^2-xy+y^2)=x^3+y^3

Answer 2

(x+y)(x²-xy+y²)= x³+y³

a) (x+y)³= x³-3x²y+3xy²-y³

b) (x-y)³= x³-3x²y+3xy²-y³

c) x³+y³= (x+y)(x²-xy+y²)

d) x³-y³= ( x - y ) ( x² + xy + y²)
