hello! I need some help, this is one of my review problems and I don't remember how to do it! So assistance would be appreciated
ladessa [460]

Answer:

  (2x^3)(3x^3 +2x +5)

Step-by-step explanation:

The key words here are "greatest common factor." They have their usual English meanings. A common factor is one that is a multiplier in every term, so you need to look to see what those are. The "greatest common factor" is the largest common factor you can find.

  first term: 2·3·x·x·x·x·x·x

  second term: 2·2·x·x·x·x

  third term: 2·5·x·x·x

A common factor is a factor that is on every list. I have shown them in bold. Once the common factor is factored out, the remaining factors are summed according to the distributive property.

 6x^6 +4x^4 +10x^3 = (2x^3)(3x^3 +2x +5)

_____

Of course you recognize that each of the coefficient numbers is even. That means they are all divisible by 2. So, you know right away that 2 is a common factor.

There are powers of x in every term. The lowest power of x is x^3, and all the other powers are higher, so you know that x^3 will be a common factor, too. Having got this far, you can factor out 2x^3 and see if any of the remaining terms seem to have anything in common. They don't.

216^-1.5t+15=1<br> please solve and give the correct answers<br> will give brainlest
LekaFEV [45]
If +15 is also a a part of the power of 216 there will be no solution:
216^(-1.5t)=1-15
216^(-1.5t)=-14
-1.5t= 216 base log -14 as log with negative value(-14 in this problem) has no solution so,
I guess it is 216^(-1.5t+15)=1 right?

216^-1.5t+15=1
-1.5t+15=216 base log 1
-1.5t+15=0(Any log with value 1 of anybase has no value which is peopwely 0)
-1.5t=-15
t=15/1.5
t=10
