Question

Factor completely: 2x^2 − 2x − 40
A.2(x − 5)(x + 4)
B.(2x − 10)(x + 4)
C.x − 5)(2x + 8)
D.2(x − 4)(x + 5)

my answer was A. On most of my questions for my homework i'm getting A so I just want to make sure that i'm doing it right.

Answer 1

when you factor out two you get
2(x^2-x-20)
so factoring it farther you would get
2(x-5)(x+4)
so yes you are right :D

Answer 2

@Hope_nicole thank you :)

Answer 3

yupp! lemme know if you need anymore help! factoring is one of those things that you just grow into, you dont really have to think about it after a while

Answer 5

haha yeah of course!

Answer 6

@Hope_nicole
Factor completely: 6x^2 + 21x + 9
A.3(2x + 1)(x + 3)
B.3(2x + 1)(x + 9)
C.(2x + 1)(3x + 9)
D.(2x + 3)(3x + 3)


What are the factors of 5x^2 − x − 6?
A.(5x − 6)(x + 1)
B.(5x − 1)(x + 6)
C.(5x − 3)(x + 2)
D. (5x − 2)(x + 3)

Answer 7

on the first one, factor 3 out and get
3(x^2+7+3)
then factor completely
3(2x+1)(x+3)
so right again!

Answer 8

the second one is a little harder
but also it is A.
so stop doubting yourself :D
