Question

What is the trinomial factor of x^3 + y^3 ?

A.) x^2 + xy +y^2
B.) x^2 - xy +y^2
C.) x^2 - xy - y^2
D.) x^3 + xy - y^2​

Answer 1

B

Explanation:

x^2-xy+y^2

Answer 2

B

Explanation:

x³ + y³ ← is a sum of cubes and factors in general as

x³ + y³ = (x + y)(x² - xy + y²)

with trinomial factor (x2 - xy + y2) → B
