Question

i need help with these problems for my homework
step by step

3x^2-x+4x

24x^2=-10x+4

(x-5)(x+4)=2(x-5)

9x^-2x+4=10x

Answer 1

What do you need to do? Solve for x?

Answer 2

i have to factor them out

Answer 3

but im not sure of where to start

Answer 4

How have you been taught to factor them? Have you learned the quadratic equation yet?

Answer 5

A quick way to check your work would be to plug each "part" or "piece" into a graphing calculator and find the zeros/interceptions.

Answer 6

i havent been taught yet i was absent last class

Answer 7

For 3x^2-x+4x can you combine any terms?

Answer 8

i dont have a graphing calculator, we're not allowed to use them in class

Answer 9

no you dont combine like terms

Answer 10

It might help to factor, but what are you suppose to do?

Answer 11

i dont know what to do thats the problem

Answer 12

How about you combine the x terms?
3x^2-x+4x

Answer 13

i think the formula is ax^2+bx+c=0

Answer 14

3x^2-x+4x=3x^2 + (4x-x)=?

Answer 15

0 ?

Answer 16

what is 4x-x=?

Answer 17

4

Answer 18

No, you can factor out the x for x(4-1), what is 4-1?

Answer 19

3

Answer 20

yes, so
3x^2-x+4x= 3x^2+(4x-x)=3x^2+3 now can you factor anything else out?

Answer 21

im not sure

Answer 22

How about the 3? 3x^2+3=3(x^2+1)

Answer 23

im lost honestly

Answer 24

Okay
Do you understand how to factor things out of equations?

Answer 25

yes

Answer 26

If you add, subtract, divide or multiply on one side of an equation you have to do the same on the other side. Sound familiar?

Answer 27

So
x^2+2x=-1 would look like what if you added 1 to both sides?

Answer 28

Let's do (x-5)(x+4)=2(x-5)
What if we divide both sides by (x-5)?
