Question

Which shows one way to determine the factors of x3 + 5x2 – 6x – 30 by grouping?

Answer 1

x(x2 + 5) – 6(x2 + 5)

Step-by-step explanation: because when u factor out you don't need to use the first number so you start with (x) and then you do multiplication

Answer 2

`x^(3) +5 x^(2) -6x-30= x^(2) (x+5)-6(x+5)=( x^(2) -6)(x+5)`

`=(x- √(6))(x+ √(6) ) (x+5)`
