One root of the polynomial P [x] = x^2 - 4x + 3 = 1. Another root of the polynomial is?
- 3
- 0
- 1
- None of these
Explanation
Given:
P(x) = x^2 - 4x + 3
One root is 1. Let's find the other root.
The sum of roots = -(-4) = 4 (from the coefficient of x)
One root is 1, so the other root would be:
4 - 1 = 3
