Question

Factorise:54x^2-96y^2

Answer 1

We have 54x2 – 96y2 = 6[9x2 - 16y2]

                            = 6[(3x)2 - (4y)2]

                            = 6 [(3x + 4y)(3x - 4y)]  [Using a2 - b2 = (a + b)(a - b)]

Thus,    54x2 - 96y2 = 6 (3x + 4y)(3x - 4y)

Answer 2

Answer:

6(3x+4y) (3x+4y)

Step-by-step explanation:

• 6[9x²-16y²]
• 6[(3x)²-(4y)²]
• 6[(3x+4y) (3x-4y)]
• 6(3x+4y) (3x -4y)

I hope my answer is right
