In the expression below, a is an integer. 12^3+ax-20 if 3x+4 is a factor of the expession above, what is the value of a

Our function is:

Now, if is a factor of then must satisfy the equation:

So,

Putting

We get,

So, the value of 'a' for the given expression is 1281.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow
