Question

Help me with this plssss
divide this​

Answer 1

1 - y + y²

Explanation:

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

a³ + b³ = (a + b)(a² - ab + b²) , then

1 + y³

= (1 + y)(1² - 1(y) + y²) = (1 + y)(1 - y + y²)

Then

`(1+y^3)/(1+y)`

=
`((1+y)(1-y+y^2))/(1+y)` ← cancel out the common factor (1 + y)

= 1 - y + y²
