Can the sum of two irrational numbers ever be a rational number?
andrew-mc [135]
Irrational numbers are numbers that can not be written<span> as a ratio of two integers.  (example: square root of 2). Rational numbers on the other hand can be written as a ratio, as decimal or percentage.
If X is a irrational number, than the number Y=1-X is also irrational and the sum of these two irrational numbers is: X+Y=X+1-X=1 is rational number.
So, the sum of two irrational numbers can be a rational number. </span>

Factor each completely <br> 5n^2-8n-21<br> 6r^2+53r-79<br> 4n^2-25
OLEGan [10]

5n² - 8n - 21    →    (5)(- 21) = -105    (find 2 numbers whose product is 105 and sum is -8)

= 5n² - 15n  + 7n - 21

= 5n(n - 3)  + 7(n - 3)

= (5n + 7)(n - 3)

*****************************************************

6n² + 53n - 79 → (6)( -79) = -474 (find 2 numbers whose product is -474 and sum is 53)  DOES NOT EXIST! only factors are: (1, 474) (2, 237) (3, 158) (6, 79)

= Prime

*******************************************************

4n² - 25   (this is the difference of two squares)

= √(4n²) +/- √(25)

= 2n +/- 5

= (2n + 5)(2n - 5)
