Answer:

i) Equation can have exactly 2 zeroes.

ii) Both the zeroes will be real and distinctive.

Step-by-step explanation:

x^{2} - 7x + 3 is the given equation.

It is of the form of quadratic equation a^{2} + bx + c and highest degree of the polynomial is 2.

Now, FUNDAMENTAL THEOREM OF ALGEBRA

If P(x) is a polynomial of degree n ≥ 1, then P(x) = 0 has exactly n roots, including multiple and complex roots.

So, the equation can have exact 2 zeroes (roots).

Also, find discriminant D = b^{2}  - 4ac = (-7)^{2}  - 4(1)(3) = 49 - 12 = 37

⇒ D = 37

Here, since D > 0, So both the roots will be real and distinctive.
