Answer 2

Hello, Buddy!!

||Required Response||

$4 {(a - 1)}^{2} - 4(a - 1) - 3 \\ 4 [{a}^{2} + {1}^{2} - 2(1)(a)] - 4a + 4 - 3 \\ 4( {a}^{2} + 1 - 2a) - 4a + 1 \\ 4 {a}^{2} + 4 - 8a - 4a + 1 \\ 4 {a}^{2} - 12a + 5 \\ 4 {a}^{2} - 10a - 2a + 5 \\ 2a(2a - 5) - 1(2a - 5) \\ (2a - 1)(2a - 5) \\ a = \frac{1}{2} \: (or) \: \frac{5}{2}$

Value of a

• $\longmapsto\;\Large{\red{\bold{\frac{1}{2}\;\&\;\frac{5}{2}}}}$
