for the first step

you basically draw a graph:

..........|

______|__

..........|

( i hope that diagram looks alright lol)

then you place the numbers in the following order (at the bottom):

..........|

______|__

3x^2 -8| +10x

after, you have to do guess and check

let me explain how:

lets say the numbers that we need will become a,b,c,d and e,f

so (try picturing the graph here too):

a.......b..|.c

d.......e..|.f

----------------

3x^2..-8..|+10x

now this is how it works:

d (times) b ( must = ) c

a (times) e ( must = ) f

now..

c (plus) f (must = ) +10x

and..

a (times) d (must = ) 3x^2

b (times) e (must = ) -8

lets try this.

i think that

a= 3x

b= 4

d= x

e= 2

we know that a*b = 3x^2. and we found out that 3x*x= 3x^2

so thats correct.

also, we knwo that b*e= 8

____________________

k im sorry but this only works for +8. oh well, do it in this manner for the following questions

and then take a and b in brackets --> (a+b) and (d+e) and

_______________________

now another way:

10 x can be written as 12x-2x

so..

3x^2 +12x-2x-8 =

(take out of brackets)

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

(remember sam brackets thing do the follwoing now:)

(x+4)(3x-2)

you done :)

3x^2 + 10x - 8 u have to space it out or - means dahs and not minus. well neway its like this ima break it down 4 u.

first u got 3x^2 + 10x - 8 then when u multiply it by 2 u got

6x^4 + 20x - 16. then u just divide it and u end up with

x + 3.33333x (this means repreating) - 2.6666666 (this also means repeating.. i duno how to do feractions on computer.)
