Factor out 15 first

Exponents first. Use PEMDAS

Parenthesis, Exponents, Multiplication, Division, Addition, then Subtraction.

anonymous · Answer

yeah an i got 3t^ -5t-5=0 @skullpatrol

skullpatrol · Answer

Try again please

unofficialllyy · Answer

I thought your question was $$15^{2}-15t-30=0$$ and if that was the case, you would do 15^2 first, since there are no parenthesis and that is the exponent. But you said the question was different.

anonymous · Answer

well i divided a 5 out of all of it 5 \15^, and 15t and 5/-30 @skullpatrol

anonymous · Answer

and no youre right thats the question i was asking ? sorry people were confusing me @Unofficialllyy

skullpatrol · Answer

Divide each term by 15

unofficialllyy · Answer

Well first you would do 15^2

anonymous · Answer

ok well in tht case i got t^-1t-2=0 from that @skullpatrol

unofficialllyy · Answer

I'm confused. What is the original question?

anonymous · Answer

the one you put down was the original @Unofficialllyy

skullpatrol · Answer

Now factor $$\Huge t^2-t-2$$

anonymous · Answer

unofficialllyy · Answer

I have to go, I'm sorry. Hopefully @skullpatrol can help!

anonymous · Answer

skullpatrol · Answer

Look for factors of -2 that add up to -1.

anonymous · Answer

i factor and i got (x-2) and (x + 1)

anonymous · Answer

@skullpatrol

skullpatrol · Answer

Very good :)

Now your equation looks like (x-2)(x+1)=0

anonymous · Answer

so i did it c:? !!

anonymous · Answer

@skullpatrol

anonymous · Answer

one last step lol

skullpatrol · Answer

Either x-2=0 or x+1=0

anonymous · Answer

anonymous · Answer

thanyouc: @skullpatrol

skullpatrol · Answer

The values of x that will make (x-2)(x+1)=0 a true statement.

Are 2 and -1.
