Question

(iv) 3 € (x:x4<br />5x3 + 2x2 - 112x + 6 = 0)​

Answer 1

Answer:

By hit and Trial, we should find the value for which the function is 0.

The value of x can not be negative.

Now putting x= 0,1,2,3,4,5,6,7 one by one we are not getting the value of the function is 0.

So, we find value between -3 to +3.

It should not be extended, because it is of no use.
