xsquared - 7x+12=0

OpenStudy (anonymous):

do know how to do factoring?

OpenStudy (anonymous):

yeah i just cant remember

OpenStudy (anonymous):

oh damn is that with the tree thing like 2 coloumns

OpenStudy (anonymous):

ok so I would do factoring let me teach you xD

OpenStudy (anonymous):

ok thanks

OpenStudy (anonymous):

but let me do it out first can you wait?

OpenStudy (anonymous):

yeah totally

OpenStudy (anonymous):

first you find 2 #'s that multiply to get 12 and would add up to 7

OpenStudy (anonymous):

do you have no guess?

OpenStudy (anonymous):

3 and 4

OpenStudy (anonymous):

right?

OpenStudy (anonymous):

yup the +12 means that the symbols are the same so they are both subtraction you split the x squared in half so like this (x-4) (x-3)

OpenStudy (anonymous):

=0

OpenStudy (anonymous):

right then what

OpenStudy (anonymous):

then you do x-4=0 and x-3=0

OpenStudy (anonymous):

the answers are x=4 or 3

OpenStudy (anonymous):

you got it right?

OpenStudy (anonymous):

thankssssssss i got it

OpenStudy (anonymous):

alsoo, what are factors of -2 that add up to 3

OpenStudy (anonymous):

what is the equation

OpenStudy (anonymous):

xsquared + 3x- 2=0

OpenStudy (anonymous):

in this equation you can't do factoring but the quadratic formula

OpenStudy (anonymous):

what are you learning now in school?

OpenStudy (anonymous):

I mean in math class

OpenStudy (anonymous):
