Question

can somebody please teach me how to factor

Answer 1

example :

Factor \(x^2 + 3x + 2\)

Answer 2

just find out two numbers such that :
product = 2
sum = 3

Answer 3

im sorry how is the sum 3?

Answer 4

constant term is 2
the middle coefficient is 3

Answer 5

lets try :

2*1 = 2
2+1 = 3

So, 2 and 1 will work

Answer 6

\(\large x^2 + 3x + 2\)

factors to

\(\large (x+2)(x+1)\)

Answer 7

we're done,
wana try another example ?

Answer 8

x2-14x+49

Answer 9

how would i factor that?

Answer 10

find two numbers such that :
product = 49
sum = -14

Answer 11

find two numbers that equal -14 and multiply to be 49 right?

Answer 12

-7?

Answer 13

yes,

-7*-7 = 49
-7 + -7 = -14

So, -7 and -7 will work

Answer 14

THANK YOU SO MUCH!

Answer 15

\(\large x^2-14x+49\)

factors to

\(\large (x-7)(x-7)\)

Answer 16

so thats how you would wrtie the answer?

Answer 17

you can simplify it to :

\(\large (x-7)^2\)

Answer 18

thank you :)

Answer 19

np :)

Answer 20

how would i do x2+11x+7

Answer 21

we cant factor it,
its called "prime"

Answer 22

thanks :)

Answer 23

u wlc :)
