Question

Solve & PLS HELP!!! PLEASE
1/4t^3-16t=0

Answer 1

do you mean like...
\[\LARGE \frac{1}{4}t^3-16t=0\]

Answer 2

Yes

Answer 3

factor out a T first

Answer 4

then you have the difference of two squares... can you factor it now?

Answer 5

Not really...

Answer 6

\[\LARGE t\cdot(\frac14 t^2-16)=0\]

now you have
t=0 or (1/4)t^2-16=0

Answer 7

Wah???

Answer 8

\[\LARGE \frac {t^2}{4}=16 \longrightarrow t^2=64\]

\[\LARGE t=\pm \sqrt{64}\]


so you have three solutions...

t=0
t=8
t=-8

Answer 9

But isn't it supposed to be two solutions?

Answer 10

not in this case... only when you have quadratic equation... here you have t^3

Answer 11

O ok then thanks

Answer 12

Never mind, Glad to help )
