4√3t+4=-6

Question

4√3t+4=-6

anonymous · Answer

ups the problem is √3t+4=-6

anonymous · Answer

you want to isolate t so its alone on one side
any idea where to start?

anonymous · Answer

this is what i have done so far (↓13t+4)^2=(-6)^2

anonymous · Answer

3t+4=36 
3t=32

anonymous · Answer

wait is your problem
$$\sqrt{3t+4}=-6$$
or 
$$\sqrt{3t}+4=-6$$
??

anonymous · Answer

first one

anonymous · Answer

oh ok
once you get 3t=32
why not divide both sides by 3?

anonymous · Answer

its ok for t to equal a fraction or a decimal

anonymous · Answer

i did and i got a fraction but my book says it should be no real solution

anonymous · Answer

what you did is completely fine and i see nothing wrong with it

maybe your book is wrong or maybe i missed something

anonymous · Answer

maybe i don't know but the problem is just like the first one you posted

@lgbasallote @jim_thompson5910 @Hero 
did i miss something or is her book wrong?

jim_thompson5910 · Answer

The square root of any positive number or zero will be positive or zero. There is no possible way to take the square root of a number and get a negative number.

jim_thompson5910 · Answer

So $$\sqrt{3t+4}=-6$$ has no solutions
