What is the complete Factorization 3x^2-75

Mathematics
1 answer:
lozanna [386]3 years ago
5 0
After a first glance you can see that 3x^2 - 75 is not a difference of squares in the current form, because for one 3 and 75 are not squares. 

So we'll have to see if we can factor something out of both of them. The only number it can be is 3, because the only number besides 3 that goes into 3 is 1. 

So is there any number that can multiply by 3 to equal 75? 

If you said 25 then you are correct. :p 

So then our problem would look like this: 
3(x^2 - 25) 

Now we have a difference of squares!

Remember a difference of squares can be factored like this!

(a^2 - b^2) = (a - b)(a + b) 

3(x - 5)(x + 5)
Is our answer!

Determine whether each number is rational or irrational.
kirill115 [55]

Answer:

where is the question.

So basically rational numbers are numbers with decimals that are not random

ex) 3.66666666,   4.040404040, 3.5645645645646

the decimals are at a fixed order

Irrational is random decimals that makes it look weird

ex)3.141592643,  5. 782759453,   8.825928342

hope that answers your question
