Question

solve the equation, and check your solution
t(4+1)=0

Answer 1

t(t-4) = 0.

You'll have to do like terms here.

t*t - 4 = 0
t^2 -4 = 0

Move the -4 to the other side and flip it.

t^2 -4+(+4) = 0+(+4)
t^2 = 4

Now we do the opposite forms.

sqrt(t^2) =4
t = sqrt(4)
t = 2

Voila. There's your answer.

Answer 2

Thanks again you're a lifesaver

Answer 3

No problem.

Answer 4

i think this answer is wrong
t(t-4)=0
t*t - t*4 = 0
t^2 - t4 = 0
t^2 = t4
t = 4 that should be the answer if i am not wrong

Answer 5

Am I seeing wrong or did she change the question? Now I see t(4+1) = 0.

Answer 6

And she's correct. I forgot all about distributing to the other number. Agh.. That's bad. Don't ever forget to distribute to "everything" that is in the parenthesis. It's a mistake made often.
