y2+8y+12=140

8y^2+ 12

y2 + 8y + 12
The idea is to get one side of the equation as Y!
So subtract 12 from this line and that will give you:
y2 + 8y = -12
Your next move is to chabge the y2 to the other side!
8y = -12 - y2
Divide by 8:
y = (-12 -y2)/8
Simplifidy!!

don't listen to the second person. their wrong.
y^2 +8y +12
(y + 6) (y + 2)
set each = 0
solve for Y.
y = -6, -2

Carol why do you want us to do your homework? This is ridiculous...Ask you teacher if you do not understand!
Anyway
Y2 +2y+ 6y +12
Y(y+2) + 6( y+2)
(Y+6) ( Y+2)
It cannot be solved because its not equal to Zero
Assuming there was equal to zero
Y= -6 and Y = -2

=y2 8y 12 because u can't unit...there is a different part letteral

you want to solve right?
factor:
look for two numbers that multiply to 12 andd add to 8
2 and 6
(x+2)(x+6)
x = -2 or -6

The whole point of teacher setting homework is to test YOUR understanding of what they have taught you..if you can't do it...say so..then the teacher will go through it again for you, but if you just copy an answer from here, (whether it's right or wrong,) and you don't understand how the answer has been reached..your teacher will THINK that YOU understand...and move on to another aspect of Maths..then when it comes to the exam...you are stuck..and you'll fail. So it is in your own interests to admit that you don't understand.

You need to define what you need to accomplish with this. Did you want to set this statement equal to zero and solve it the solutions are: -2 and -6. You can also state this another way:
(y+2)(y+6)
You can use the quadratic equation solver at:

to check your answers
