Question

x2 - x - a (a + 1) = 0​

Answer 1

Step-by-step explanation:

Given: x2 – x –a(a + 1) = 0 ⇒ x2 – x – a2 – a = 0 ⇒ (x2 – a2 ) – (x + a) = 0 ⇒ (x + a)(x – a) – (x + a) = 0 [∵ a2 – b2 = (a + b)(a - b) ] ⇒ (x + a)[(x – a) – 1)] = 0 ⇒ (x + a) = 0 or (x – a) – 1 = 0 ⇒ x = – a or x = (a + 1)

Answer 2

2x-x-a(a+1)=0

x-a^2-a=0
