Question

FACTORISE:
1.4a²+20a-96

THE ANSWER MUST BE
4(a-3) (a+8)​

Answer 1

Answer:

$4(a - 3)(a + 8)$

Step-by-step explanation:

$4 {a}^{2} + 20a - 96 = 4( {a}^{2} + 5a - 24) \\ = 4( {a}^{2} + 8a - 3a - 24) \\ = 4(a(a + 3) - 3(a + 8)) \\ = 4(a - 3)(a + 8)$

Answer 2

${4a}^{2} 2+20a−96 \\ = 4(a - 3)(a + 8)$
