Q. 17: The number of integers that satisfy the equality (x2 – 5x + 7)x + 1 = 1 is
Correct Answer 3 (Option 3)
We can have three possibilities for the equality of form = 1
First n = 0, then x = 1 and then x = -1 and n = even
Using first x = -1, and substituting in given equation
Solving x = 2 or x = 3 (Both are acceptable)
No integer values,
So 3 values satisfy the equality
