The two solutions of 2x squared +1 =5x are j and k. what is the value of (j-1)(1-k)

We have two pairs of answers :
1st pair : j=(5+sqrt(17))/4 & k=(5-sqrt(17))/4
2nd pair : j=(5-sqrt(17))/4 & k=(5+sqrt(17))/4
If you look carefully , both of the answers are merely the same , they inly switched between the - and + .
For the first and second pairs , you will get only one answer for (j-1)(1-k) , which is 1

f we start with 6 and 8, we can break 6 up into 2*3 and 8 into 2*2*2, thus getting a prime factorization of 2*2*2*2*3, or 2^4 *3.

If we begin with 4 and 12, 4 breaks into 2*2 and 12 into 2*2*3, so the prime factorization of 48 is still 2^4 *3.

The starting factors do not matter, since the answer comes out to be the same. There is exactly one correct answer- it doesn't matter how it's found.

Hope this helps! :)
