Question

~~~~~GIVING OUT A MEDAL AND FANNING ANYONE WHO HELPS ME THANK YOU ^_^!!!!~~~~~
Factor completely: 2x3 + 10x2 + 4x + 20

2(x3 + 5x2 + 2x + 10)

2[(x + 5)(x2 + 2)]

(2x + 10)(x2 + 2)

(x + 5)(2x2 + 4)

Answer 1

@jazzyfa30

Answer 2

First, there is a common factor among all terms. Do you see why we can factor out a 2 from everything?

Answer 3

Yeah

Answer 4

The two can go into any of those

Answer 5

I think

Answer 6

2(x^3 + 5x^2 + 2x + 5)

Answer 7

let me check if it's right

Answer 8

2x3 + 10x2+ 4x + 20
What's common in this?
2(x^3+5x^2+2x+10 )

Answer 9

I'm going to make an educated guess because i'm just learning this but I believe you divided everything by two

Answer 10

Ya..

Answer 11

So that's the answer?

Answer 12

Unfortunately not.

Answer 13

Oh... where did I go wrong?

Answer 14

-5,1.41,-1.43

Answer 15

? whats that?

Answer 16

-5,1.41,-1.43

Answer 17

@Rezwanahmed and @50_cent u have solved the cubic equation which is not mentioned here

Answer 18

value of x

Answer 19

I just solved it.It's A.

Answer 20

Lol @saifoo.khan said it was wrong but I need an explanation for how its wrong

Answer 21

That wasn't completely factorized.

Answer 22

@HelloGoodmorning as there is no common coming out.use alternative method.

Answer 23

the 2nd one

Answer 24

2[(x + 5)(x2 + 2)]

Answer 25

Oh ok @saifoo.khan and @heybhai what is the alternative method and @jazzyfa30 can you explain how you got the answer to that

Answer 27

Oh ok

Answer 28

2(x3 + 5x2 + 2x + 10)

2[x^2(x+5) +2(x+5)
2(x+5)(x^2+2)

Answer 29

(2x+10)(x^2+2)

Answer 30

so @Rezwanahmed thats the answer?

Answer 31

B is the answer.

Answer 32

Answer is E.

Answer 33

no it isn't it is B

Answer 34

e? @saifoo.khan

Answer 35

value of x

Answer 36

@Rezwanahmed what value of x?

Answer 37

@HelloGoodmorning if u wanna solve this assuming this as an equation then solution for any cubic equation ax^3+bx^2+cx+d=0.
assume M,N and O as
M+N+O= -b/a
MN+NO+OM=c/a
MNO=-d/a
solve them and get the solution

Answer 38

dude u must be crazy think im boutta sit here and solve that i got my own math work to do like i said the answer is B and that's that

Answer 39

(2X+10)(x2+2)I think it is answer

Answer 40

I think so too @Rezwanahmed

Answer 41

Its a pretest im not to worried i dont know why they did a pretest before you learn the lesson but it still counts as a grade
