Question

factorize x² + 2x - (2a + 3) (2a + 1)​

Answer 1

Answer:

(x - 4a) ( x + 4a + 2)  - 3

Step-by-step explanation:

x2 + 2x - {(2a + 3) (2a + 1)}

x2 + 2x - {4a2 + 8a + 3}

x2 + 2x -4a2 - 8a - 3

x2 - 4a2 + 2x - 8a - 3

(x + 4a) (x - 4a) + 2x - 8a -3

(x + 4a) (x - 4a) + 2(x - 4a) -3

(x - 4a) ( x + 4a + 2)  - 3

Hope it helps :D
