1. Find the roots of the following polynomial equations.
| S.No | Polynomial equations | Root of the polynomial |
| (i) | \(5x - 3 = 0\) | \(x =\) |
| (ii) | \(-7 - 4x = 0\) | \(x =\) |
(Note: Insert negative sign if necessary in the numerator itself.)
2. Check whether \(-3\) and \(3\) are zeros of the polynomial \(x^2 - 9\).
Answer:
Let \(f(x) = x^2 - 9\).
\(f(-3) =\)
\(f(3) =\)
Therefore, \(-3\) and \(3\) are \(x^2 - 9\).
