2x(3x-4) = 0
this is like saying 2x * (3x-4) = 0
factors are:
2x=0 and 3x-4=0
solve for x:
x=0 and 3x=4
x=0 and x= 4/3
0, 4/3

It is already factored, but this is the solution:
if x*y=0, then either x or y = 0 or they both = 0, so
2x=0, x=0/2, x=0
or
3x-4=0, 3x=4, x=4/3, x=1+1/3

OK start here
x times x = x^2 that is x squared or x times itself
so x(x+1) would equal x^2+x
Now 2X(x+1) would equal 2x^2+2x
so now 2x(3x-4) would equal 6x^2-8x
Hopes it helps

I even have, yet i'm a Buddhist so i don't count variety. in this communicate board there's a regular head butting of fact against concept with the believers attempting to distort fact to assist concept and the logicians (for elect of a extra useful be conscious) attempting to us fact to instruct the non life of something religious which the believers sense is self reliant of any info. you're able to desire to look at most of the questions approximately evolution as against creation to work out the way all of them distort issues to wholesome the requirement to instruct info that they are good. very few human beings look in a position to easily say that they don't understand all the solutions.

First you distribute.
2x times 3x =6x^2
2x times ( -4 )= -8x
6x^2 - 8x

2x(3x-4)
multiply 2x and 3x
then multiply -4 and 2x
answer is 6x^2-8x

Set each part equal to zero.
2x = 0 or 3x-4 = 0
Solve each separately.
2x = 0
Divide both sides by 2.
x = 0/2 = 0
3x-4 = 0
Add 4 to each side
3x = 4
Divide both sides by 3
x = 4/3
Answer: x = 0 or x = 4/3

2x(3x-4)=0
2x times 3x - 2x times 4 = 0
6x squared -8x =0
6x squared = 8x
6x = 8
x = 1 1/3

You take 3x4 which =12. then12x2 which =24 Well I'm not sure kid but, maybe you can ask a teacher

2x(3x-4)=0
multiply 2x by 3x and -4, you get this
6x^2 - 8x=0
thats as far as you can go
