Question

1)What is the remainder , when X²⁵ - 25 is divided by X + 1?
ex -26
-24
0
1

2)If a/b = 5/6, then find the value of 7a/3b.
ex 6/5
12/9
35/18
2/2​

Answer 1

1) r = x^24 - 25 by doing long division process

2). a/b = 5/6 => a = 5x and b = 6x where x is a common factor of a and b.

=> 7a = 35x and 3b = 18x

lastly, 7a/3b = 35x/18x = 35/18
