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

D

Step-by-step explanation:

Given

x³ + 5x² - 6x - 30 ( factor the first/second and third/fourth terms )

= x²(x + 5) - 6(x + 5) ← D

factor out (x + 5) from each term

= (x + 5)(x² - 6) ← in factored form

Option D.

Step-by-step explanation:

The given expression is x³ + 5x² - 6x - 30

Now we have to factorize it by grouping.

So (x³ + 5x²) - (6x+30)

By solving x² (x+5) - 6(x + 5)

Therefore, Option D is the answer.
