Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients. - (i) `x^2-2x-8` (ii) `4s^2-4s+1` (iii) `6x^2-3-7x` (iv) `4u^2+8u` (v)`t^2-15` (vi) `3x^2-x-4`

Explanation

To find the zeroes of the given quadratic polynomials and verify the relationship between the zeroes and the coefficients, we will follow a systematic approach for each polynomial.

### (i) Polynomial: \( x^2 - 2x - 8 \)

1. **Set the polynomial to zero:**
\[ x^2 - 2x - 8 = 0 \]
