Given quadratic polynomial is 4x2 – 4x – 3. 

For zeros of quadratic polynomial, 4x2 – 4x – 3 = 0 . 

⇒ 4x2 – 6x + 2x –3 = 0 

⇒2x (2x –3) + 1 (2x –3) = 0 

⇒ (2x + 1) (2x –3) = 0 

⇒ 2x + 1 = 0 or 2x – 3 = 0

⇒ x = - \(\frac{1}2\) or x = \(\frac{3}2\).

Hence, the zeros of the quadratic polynomial are - \(\frac{1}2\) and \(\frac{3}2\).
