Factorize \( a^2 − b^2 − 4a + 4 \)
A
(a + b)(a − b)
B
(a − 2 + b)
C
(a + 1)(a − 2 + b)
D
(a + b) 2
Ask EduPadi AI for a detailed answer
Correct Option: B
The trinomial = \( a^2 − 4a + 4 \\
a^2 − b^2− 4a + 4 = (a^2 − 4a + 4) − b^2 \\
(a^2 − 2a − 2a + 4) − b^2 \\
a(a − 2)− 2(a − 2)] − b^2 \\
(a − 2)2 − b^2 \\
(a − 2 + b)(a − 2 − b )\)
