Help! Guys I don't know how to solve a Polynomial!

OpenStudy (anonymous):

it depends in the ques

jhonyy9 (jhonyy9):

???

OpenStudy (anonymous):

for say like 3x+2x-11

jhonyy9 (jhonyy9):

3x+2x=5x 5x-11=0 5x=11 x=11/5

OpenStudy (anonymous):

What???

jhonyy9 (jhonyy9):

assum 3x+2x=5x

jhonyy9 (jhonyy9):

ok ?

OpenStudy (anonymous):

ok

jhonyy9 (jhonyy9):

good luck bye

OpenStudy (anonymous):

uh thanks but I still don't understand

jhonyy9 (jhonyy9):

what and why ?

OpenStudy (anonymous):

Because you didn't exactly talk me through it

OpenStudy (anonymous):

I learn by being talked through

jhonyy9 (jhonyy9):

so if there are 3x+2x-11 on first step you make this equal by zero so 3x+2x-11=0 - now add to both sides 11 so 3x+2x-11+11=11 3x+2x=11 so assum 3x+2x so 5x=11 so divide both sides by 5 5x/5 =11/5 x=11/5

jhonyy9 (jhonyy9):

now is right ?

OpenStudy (anonymous):

yup

jhonyy9 (jhonyy9):

ok good luck
