Question

4z² -8z +3 = ?
(a) (2z- 1)(2z-3)
(c) (2z + 3) (3z - 1)
(b) (2z +1)(3-2z)
(d) (z - 1)(4z-3)​

Answer 1

Answer:

$4z {}^{2} - 8z {}^{2} + 3 = 4 \\ = 4z {}^{2} - 6z - 2z - 3 \\ = 2z(2z - 3) \\ =( 2z - 1)(2z - 3)$

Step-by-step explanation:

Therefore, option a is correct.

Answer 2

Answer:

(9z²-1-8z)-(2z+3+4z²)

Step-by-step explanation:

(9z²-1-8z)-(2z+3+4z²)
