multiply 3t with (t-5) 6t 2? means?
Atsie
  • Atsie
as in 3x5? are you saying do that?
smilie2015
  • smilie2015
3t*t-3t*5 got it ..

t means 1 correct? Or does t even mean anything
smilie2015
  • 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? :)

Well they are algebraic constants used widely for solving equations.
Atsie
  • Atsie
Ahh, I understand that part. So do I just do 3 x 5 and then minus it by three?
smilie2015
  • smilie2015
it will be as multiply 3t with both values \[3t ^{2}-15t\]
Atsie
  • Atsie
3 x 3 is 9 then I'll minus that by 15... and thats 6
smilie2015
  • smilie2015
u r given the value of "t"?
Atsie
  • Atsie
the value of t is 1?
smilie2015
  • 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

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
  • smilie2015
\[3t ^{2}-15t+6t ^{2}\] \[9t ^{2}-15t\]
smilie2015
  • smilie2015
got it?
Atsie
  • 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
  • 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
  • smilie2015
you got this step?
Atsie
  • Atsie
Leave t as is, your saying. I got that :)

smilie2015
  • smilie2015
yup t will only get square when it is multiplied twice then \[3t ^{2}-15-6t ^{2}\]
smilie2015
  • smilie2015
15t sorry
smilie2015
  • smilie2015
+6t square
Atsie
  • Atsie
15 + 6 x 6?
Atsie
  • Atsie
I'm sorry for being such a pain, I'm slow at this
smilie2015
  • smilie2015
same degree will be add up \[3t ^{2}+6t ^{2}-15t=9t ^{2}-15t\]
smilie2015
  • smilie2015
ohhh no problem :)

\[3t2+6t2−15t\] when all equated it comes out to 30.
smilie2015
  • smilie2015
how?
Atsie
  • Atsie
is that right?
smilie2015
  • smilie2015
how you do that ?
Atsie
  • Atsie
I did 3 x 3 + 6 x 6 - 15
smilie2015
  • smilie2015
why u r putting values in "t" place?
Atsie
  • 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
  • smilie2015
it is not (3t)^2 it is only 3t*t which means t is two times only t will be sqaured
smilie2015
  • smilie2015
got the point?
Atsie
  • Atsie
So at what point do I square the 't' in the equation?
smilie2015
  • smilie2015
3t*t=3t^2 got ?
Atsie
  • Atsie
But whaaat is "t" though? Why would I square it if its nothing.
Atsie
  • Atsie
I feel so bad because I'm taking five years just to understand this
smilie2015
  • smilie2015
Well they are algebraic constants used widely for solving equations.
smilie2015
  • smilie2015
like x if u had studied algebra
Atsie
  • Atsie
Yeah I understand all that, it really just mixes me up a lot though.
smilie2015
  • smilie2015
ok u got the answer of the above question?
Atsie
  • Atsie
yes I did
smilie2015
  • smilie2015
ok then bye :)
