Answer:
2
Explanation:
Since the polynomial is of degree 2, there will be 2 roots
To find the roots let y = 0, that is
x - 4x² + 3x = 0
4x - 4x² = 0 ← factor out 4x on the left side
4x(1 - x) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
1 - x = 0 ⇒ x = 1
The 2 roots are x = 0 and x = 1
