Question

Please help!!! I need to factor the expression by grouping, but I messed up and gave an equation instead

Answer 1

Given the expression

`y^3-4y^2-8y+32`

Take outside the square of y from the first two terms and -8 and from the last two terms.

`y^2(y-4)-8(y-4)`

The term y-4 is common. So, take it outside.

`(y^2-8)(y-4)`
