Question

The factorisation of 36x^2y^2 – 1 is​

Answer 1

Answer:

(6xy-1)(6xy+1)

Step-by-step explanation:

First, calculate the product

That's equals 6^2x^2y^2-1^2

The second factor is the expression

And that's equal to (6xy) ^2-1^2

Lastly distribution property

(6xy-1) (6xy+1)

Answer 2

Answer:

(6xy+1)*(6xy-1)

Step-by-step explanation:

36x²y²-1

=(6xy) ²-1²

=(6xy+1)*(6xy-1) {a²-b²= (a+b) *(a-b)}
