1.	4z2 – 8z + 3=? A. (2z – 1) (2z – 3) B. (2z + 1) (3 – 2z) C. (2z + 3) (3z + 1) D. (z – 1) (4z – 3)
Answer» 4z² – 8z + 3 Factorizing the equation and taking 2z and – 1 as common, = 4z² – 6z – 2z + 3 = 2z(2z – 3) – 1(2z – 3) = (2z – 1)(2z – 3).

4z2 – 8z + 3=? A. (2z – 1) (2z – 3) B. (2z + 1) (3 – 2z) C. (2z + 3) (3z + 1) D. (z – 1) (4z – 3)

Answer»

4z² – 8z + 3

Factorizing the equation and taking 2z and – 1 as common,

= 4z² – 6z – 2z + 3

= 2z(2z – 3) – 1(2z – 3)

= (2z – 1)(2z – 3).
