multiply 3t with (t-5)
6t 2? means?

- Atsie

as in 3x5? are you saying do that?

- smilie2015

3t*t-3t*5
got it ..

t means 1 correct? Or does t even mean anything

- smilie2015

\[3t \times t-3t \times5\]
t is not 1 it can be any number but when u are not given any number if it is not defined u will not put any other number in it
for example if u r given to put t=2
u can solve and put the value in it
but like the above question u will only simplify will not put any number in "t" place
got it? :)

- smilie2015

Well they are algebraic constants used widely for solving equations.

- Atsie

Ahh, I understand that part. So do I just do 3 x 5 and then minus it by three?

- smilie2015

it will be as
multiply 3t with both values
\[3t ^{2}-15t\]

- Atsie

3 x 3 is 9 then I'll minus that by 15...
and thats 6

- smilie2015

u r given the value of "t"?

- Atsie

the value of t is 1?

- smilie2015

u r given in question
plz share full question soo it can help
if value of t is not given u cannot assume it

- Atsie

Simplify the expression.
\[3t(t - 5) + 6t 2\]
And here are the options I am given...
A. \[-12t + 6t2\]
B. \[9t2 - 15t\]
C. \[9t2 - 5\]
D. \[24t\]

- smilie2015

\[3t ^{2}-15t+6t ^{2}\]
\[9t ^{2}-15t\]

- smilie2015

got it?

- Atsie

3 x 3 is 9
9 - 15 is 6
6 x 6 is 36
I am confusing myself out of existence. Maybe I'm being to literal with how this should be solved.
I see that you rearranged the order of the equation, how did doing that make the answer come out?
Could you just completely step by step on how you got to that answer and then maybe I might understand it then.

- smilie2015

ok look t=t nor 3 nor 6
so when we multipy 3t with (t-5)
3t*t - 3t*5
soo dont touch t
t*t will be t square

- smilie2015

you got this step?

- Atsie

Leave t as is, your saying. I got that :)

- smilie2015

yup t will only get square when it is multiplied twice
then \[3t ^{2}-15-6t ^{2}\]

- smilie2015

15t sorry

- smilie2015

+6t square

- Atsie

15 + 6 x 6?

- Atsie

I'm sorry for being such a pain, I'm slow at this

- smilie2015

same degree will be add up
\[3t ^{2}+6t ^{2}-15t=9t ^{2}-15t\]

- smilie2015

ohhh no problem :)

- smilie2015

got it?

you can get help from here also..

- Atsie

\[3t2+6t2−15t\] when all equated it comes out to 30.

- smilie2015

how?

- Atsie

is that right?

- smilie2015

how you do that ?

- Atsie

I did 3 x 3 + 6 x 6 - 15

- smilie2015

why u r putting values in "t" place?

- Atsie

No I didn't put values in the "t" place, I just did the "2 squared part"
Ain't that what you supposed to do. Cause if not, why is it there in the first place?

- smilie2015

it is not (3t)^2 it is only 3t*t
which means t is two times only t will be sqaured

- smilie2015

got the point?

- Atsie

So at what point do I square the 't' in the equation?

- smilie2015

3t*t=3t^2
got ?

- Atsie

But whaaat is "t" though? Why would I square it if its nothing.

- Atsie

I feel so bad because I'm taking five years just to understand this

- smilie2015

Well they are algebraic constants used widely for solving equations.

- smilie2015

like x if u had studied algebra

- Atsie

Yeah I understand all that, it really just mixes me up a lot though.

- smilie2015

ok u got the answer of the above question?

- Atsie

yes I did

- smilie2015

ok then bye :)

- Atsie

Thanks for being patient

- smilie2015

ohhh no problem i am here for helping you :)
