Question

how to factorise 32 x square y square - 8​

Answer 1

Step-by-step explanation:

Answer: 2 (4x + 3y) (4x - 3y)

32x

2

−18y

2

We can also write this equation as,

(2^{5} * x^{2} ) - (2*3^2*y^2)(2

5

∗x

2

)−(2∗3

2

∗y

2

)

Now, pull out like terms,

2(16x2 - 9y2)2(16x2−9y2)

Now, using a²-b² = (a+b)(a-b) we'll get,

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