What is the factored form of 3x

+ 21x – 24?
(1 point)
2
3(x + 8)(x – 1)
3(x + 6)(x – 3)
3(x + 5)(x – 3)
3(x + 7)(x – 3)

wrong again.

3x^2 + 21x – 24 = 3(x^2+7x-8) = 3(x+8)(x-1)

Apologies for the error in my previous response. The correct factored form of 3x^2 + 21x - 24 is indeed 3(x + 8)(x - 1). Thank you for pointing out the mistake.

3(x + 6)(x - 3)
