(x + 3)(x^2 + 5x – 4)
= x^3 + 5x^2 - 4x + 3x^2 + 15x - 12
= x^3 + 8x^2 + 11x - 12

Factor: x2 + 3x + 7x + 21 User: Factor: x2 – 1 User: Factor: 4x2 – 81y2
Weegy: 4x2 – 81y2 = (2x - 9y)(2x + 9y) User: Factor: x2 – 11x + 18 Weegy: x2 – 11x + 18 = (x-9)(x-2) (More)

farrukh-expert, please carefully check conversation with multiple questions. Sometimes the questions are just the same. Moderators will edit out unnecessary notes and repeated question to make the conversation clear.

the factors are (x + 3) (x + 7) not (x - 3) (x - 7)
because it will make it as x^2 - 7x - 3x + 21 which will become x^2 - 10x + 21 (see its minus not plus) whole equation goes wrong if its mistakenly involve minus instead of plus

thanks jeifunk for understanding this thing. i was continuously pointing out thing but was unable to make you understand.

I am referring to the first question. You answer is right. My apologies.
User: Factor: x2 + 3x + 7x + 21
Weegy: X2-10x+21 = (x-3)(x-7)

The answer should be positive : X2 + 10x + 21 = (x + 3)(x + 7)
