329. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
6 straight x squared minus 3 minus 7 straight x
      
     


We have,6x2–7x–3 = 6x2– 9x + 2x – 3
= 3x(2x – 3) + 1(2x – 3)
= (3x + 1) (2x – 3)
So, the value of 6x2 – 7 – 3 is zero when (3a + 1) = 0 or (2x – 3) = 0
