Question

factorisation: x^2-y^2-6ax+2ay+8a^2​

Answer 1

Step-by-step explanation:

Given,x2 – y2 – 2(3ax) + 2ay + 9a2 – a2

⇒ x2 – 2(3a)(x) + (3a)2 – (a2 – 2ay + y2)

⇒ (x – 3a)2 – (a – y)2

⇒ (x – 3a – a + y)(x – 3a + a – y)

[Since, from the identity III we know that, (x2 – y2) = (x – y)(x + y)]

⇒ (x – 4a + y)(x – 2a – y)

Answer 2

Answer:

Step-by-step explanation:

Given,x2 – y2 – 2(3ax) + 2ay + 9a2 – a2

⇒ x2 – 2(3a)(x) + (3a)2 – (a2 – 2ay + y2)

⇒ (x – 3a)2 – (a – y)2

⇒ (x – 3a – a + y)(x – 3a + a – y)

[Since, from the identity III we know that, (x2 – y2) = (x – y)(x + y)]

⇒ (x – 4a + y)(x – 2a – y)
